7. Description of Functions
7.1 Dimming Function
S6AL211 series are integrated with 4channels LED-lighting dimming circuits.
The change in the brightness of the LED, the combination of current dimming (i.e. change the LED current) and the PWM dimming
(i.e. change the turning on and off time of the LED) is possible. As a result, you can choose the best dimming type for your
application.
Dimming Type B:
It is a dimming method that controls the LED current by brightness setting data. By the LED continuously lighted, flicker-free
application can be realized. In addition, FET of the PWM dimming is not required for reduce the BOM.
Dimming Type C:
By adding the PWM dimming to the current dimming, providing deep dimming that expands the dynamic range of brightness. It can
output a brightness of less than 1% by the PWM dimming.
Figure 7-1 Dimming Type
Brightness of the LED, you can change the setting through the following equipment.
Setting from the communication module (DALI, UART (Bluetooth module))

7.2 Constant Current Control
S6AL211 series are integrated with 4ch. constant current control circuit. It based on the step-down (Buck) DC / DC converter.
DC / DC converter generates VOUT voltage from VIN voltage by controlling the ON / OFF duty of external switching FET (Pch.)
which connected to DRV_n terminal.
The LED current (ILED) of lighting LED depend on the VF-IF characteristics of the LED. The ILED value is converted into voltage by
the detection resistor Rs, and is feedback to the control circuit from CS_n terminal. A control circuit compares and controls the ILED
current coincided with the target current value by changing output voltage VOUT.
In the case of only current control (Dimming type B), external PWM FET (Nch.) is not necessary.

7.5 Protection Function
S6AL211 series are integrated with various protection functions. Protection function has 10 protection functions and 4 protection
states.
When the protection factor (i.e. Measurement target in for protection) in each protection function exceeds protection conditions (i.e.
Detection value and number of detected), it moves to a protection mode. In the protection mode, function of reduce the lighting or
lights off, and function of IC operation stop are performed. As a result, the LED circuit and the power supply circuit are protected
safely.
Note:
In addition, we have implemented safety considerations by being integrated with various protection functions. However, to prevent
smoke or ignition if circuit is failure such as broken the external FET or the IC, should mount the protection circuit or fuse at the
power supply circuit.
7.5.1 Protection States
S6AL211 series have the following 4 protection states.
Dimming Protection, Lights out Protection-1, Lights out Protection-2 and Lights out Protection-3
Reducing LED output current and Keeping lighting-ON to eliminate the protection conditions
Dimming Protection : Lights down operation which reduce the LED output current of 10% from 100% brightness
“Protection release wait time” is assigned by the Protection States. When during “Protection release wait time” ignores request of
brightness increase from communication interfaces (UART and sensor input ) (Request of brightness reduce or lights-off are
enabled). (*1)
If the protection condition is detected again during “Protection release wait time”, adds the Lights down operation. It reduces the
LED output current of 10% from 100% brightness. In addition, it resets the “Protection release wait time”.
If lights out ( LED output current is zero) as a result of the Dimming Protection, IC moves to the Lights out Protection-2 state.
When the protection condition is not detected again during “Protection release wait time”, IC moves to the Normal state. And
reduced brightness by the Lights down operation is maintained until received the new brightness from communication interface.
Lighting-OFF, if the circuit behavior is abnormal or the protection condition is not eliminated by Dimming Protection
Lights out Protection-1: Lights out operation
After Lights out and “Restart wait time”, IC is initialized for return from the protection state and restarted lighting operation (auto
restart). (*2)
When IC receives communication from communication interface (DALI and UART ) during “Restart wait time”, IC is initialized
and restarted immediately. (*2)
Lights out Protection-2: Lights out operation
It does not restart automatically. (latch off)
When IC receives communication from communication interface (DALI and UART), IC is initialized and restarted. (*2)
Lights out Protection-3: Lights out and Shutdown of IC operation
IC maintains the protection (Shutdown) state until eliminated of the protection conditions.
To avoid the failure operation, IC stops functions other than protection and moves to the shutdown.
When eliminated of the protection conditions, IC is initialized and restarted (auto restart). (*2)
*1: When DALI products, during “Protection release wait time” of Dimming Protection, received brightness set to memory and do not
change the brightness. After “Protection release wait time”, changes to the brightness that stored value.
*2: When DALI products, restart to “POWER ON LEVEL”.

Internal Over Temperature Protection and Internal Over Temperature Shutdown
This function protects the failure operation or IC breakdown by cause of the IC high temperature.
Protective factor is the temperature value which measured IC Internal Temperature.
If temperature value exceeds the “Internal Over Temperature Protection Detection Temperature”, “Dimming Protection” is
performed as the “Internal Over Temperature Protection”.
If temperature value exceeds the “Internal Over Temperature Shutdown Detection Temperature”, “Lights out Protection-3” is
performed as the “Internal Over Temperature Shutdown”.
VO Under Voltage Protection
This function protects the failure operation which connected circuit to VO pin such as temperature sensor, communication circuit
by cause of the LDO under voltage.
Supply the power from VO to external temperature sensors for detects the VO Under Voltage protection by TEMPx terminals.
Protective factor is the TEMPx input voltage value that relates the VO output voltage value.
If VO output current value exceeds the “Maximum Output Current”, the LDO Over Current Limit function performed reduce the VO
output voltage and current by the conventional fold-back current limiting characteristic, it detected by TEMPx terminals.
If TEMPx value is under the ‘VO under voltage Protection Detection Voltage’, ‘Dimming Protection’ is performed as the ‘VO Under
Voltage Protection’. It shares the operation with ‘External Over Temperature Protection’.
7.5.3 Function of Protection Status Output
S6AL211 series has a feedback output pin (PCNT) for outputting to an external IC. It informs moved to the protection states (Lights
out Protection-1, -2 and -3) which has safety problem.
It can be used as a signal which informs the failure lighting to the MCU in the lighting system.

S6AL211 Series
7.6 Standby Function
S6AL211 series are integrated with the standby function.
It reduces the power consumption of the IC by stops the functions other than minimum necessary functions.
Move to the Standby State
When the all channels brightness is set to the Lights out (0% brightness), the LED current flow turns to 0A.
Then IC moves to the Standby state after the “Standby transition wait time”.
When IC receives communication from communication interface or input from sensors during the “Standby transition wait time”, IC
returns to the Normal Dimming Operation.
And, IC does not move to the Standby state from Lights out by protection function.
Standby State
It is a state of low power consumption. IC stops functions other than the communication interface and sensor inputs for acceptance
of return to the Normal Dimming Operation.
3V LDO continues an output.
Return to the Normal State from Standby State
When IC receives communication from communication interface or sensor inputs, IC returns to the Normal Dimming Operation.

7.7 Power-on and Power-off
When power is supplied to the S6AL211 series, the constant current control circuit outputs a stable output current to within 0.3s after
reaching the recommended operating voltage.
(When don't use the Fade function and DALI, Not include 0.6s of waiting time for the Power Level command.)
After the Power-on, the brightness becomes to the set value "POWER ON LEVEL". (Please refer to the hardware manual of each
IC: S6AL211A21, S6AL211A31 and S6AL211A94 for "POWER ON LEVEL".)
If the power supply is stopped without Lights out setting, IC stops switching operation of the constant current control circuit safely by
functions of the Input Low Voltage Protection and the Input Under Voltage shutdown.

7.8 LDO
S6AL211 series are integrated a 3V LDO regulator for supplying the power to the peripheral circuits. It can be used, for example, the
power supply of the sensors (temperature sensor, ambient light sensor, human motion detect sensor), PullUp power of I2C Bus and
the power supply of the communication module. Therefore it reduces the BOM cost, reduces board mounting area and realizes the
other power ICs unnecessary.
LDO continues an output in standby state.
VO pin must be connected to a bypass capacitor.
If the output current of the LDO becomes over current, reduce the output voltage and current by the conventional fold-back current
limiting characteristic.
7.9 External Inputs for Dimming
S6AL211A94 corresponds to external input for dimming function of the following.
Ambient light sensor Input: SENSE3 (ADD3) Pin
Trigger Input (Human Motion detect sensor): SENSE4 (ADD4) Pin
7.9.1 Ambient Light Sensor Input Dimming (SENSE3/ADD3 Pin)
It operates the dimming control by the ambient light sensor input.
Please refer to the S6AL211A94 hardware manual for details.
7.9.2 Trigger Input Dimming (SENSE4/ADD4 Pin)
It operates the dimming control by trigger signal from the motion (human detect) sensor.
Please refer to the S6AL211A94 hardware manual for details.

10. Usage Precautions
Do not configure the IC over the maximum ratings.
If the IC is used over the maximum ratings, the LSI may be permanently damaged.
It is preferable for the device to normally operate within the recommended usage conditions. Usage outside of these conditions can
have an adverse effect on the reliability of the LSI.
Use the device within the recommended operating conditions.
The recommended values guarantee the normal LSI operation under the recommended operating conditions.
The electrical ratings are guaranteed when the device is used within the recommended operating conditions and under the
conditions stated for each item.
Printed circuit board ground lines should be set up with consideration for common impedance.
Take appropriate measures against static electricity.
Containers for semiconductor materials should have anti-static protection or be made of conductive material.
After mounting, printed circuit boards should be stored and shipped in conductive bags or containers.
Work platforms, tools, and instruments should be properly grounded.
Working personnel should be grounded with resistance of 250 kΩ to 1 MΩ in serial between body and ground.
Do not apply negative voltages.
The use of negative voltages below - 0.3V may make the parasitic transistor activated to the LSI, and can cause malfunctions.
11. RoHS Compliance Information
This product has observed the standard of lead, cadmium, mercury, Hexavalent chromium, polybrominated biphenyls (PBB), and
polybrominated diphenyl ethers (PBDE).
