3D Magnetic Sensor
Functional Description
2 Functional Description
2.1 General
Description of the Block diagram and its functions.
Figure 2 Block Diagram
The IC consists of three main function units containing the following building blocks:
• The power mode control system, containing a low-power oscillator, basic biasing, accurate reset,
undervoltage detection and a fast oscillator.
• The sensing part, containing the HALL biasing, HALL probes with multiplexers and successive tracking ADC.
Furthermore a temperature sensor is implemented.
•The I2C interface, containing the register file and I/O pads.
2.1.1 Power Mode Control
The power mode control provides the power distribution in the IC, a power-on reset function and a specialized
low-power oscillator clock source. Additionally it is handling the start-up behavior.
• On start-up this unit:
– activates the biasing, provides an accurate reset detector and fast oscillator.
– interprets the applied voltage level on ADDR pin as logical “0” or “1”. This determines one of two
possible I2C bus addresses to access the sensor.
– sensor enters power down mode (configured via I2C interface).
Note: After supplying the sensor (= power up) the sensor enters the mode power down by default.

TLV493D-A1B6
3D Magnetic Sensor
Functional Description
• After re-configuration to one of the operating modes a measurement cycle is performed regularly
containing of:
– starts the internal biasing, checks for reset condition and provides the fast oscillator
– provides the HALL biasing
– the measurement of the three HALL probe channels sequentially incl. temperature (default = activated)
– and enters the configured mode again
In any case functions are only executed if the supply voltage is high enough, otherwise the reset circuit will halt
the state machine until the level is reached and restarts its operation afterwards. The functions are also
restarted if a reset event occurs in between.
2.1.2 Sensing Part
Performs the measurements of the magnetic field in X, Y and Z direction. Each X, Y and Z-HALL probe is
connected sequentially to a multiplexer, which is then connected to an Analog to Digital Converter (ADC).
Optionally, the temperature is determined as well after the three HALL channels. The current consumption
decreases by -25 % when temperature measurement is deactivated.

3D Magnetic Sensor
Functional Description
2.5 Application Circuit
The use of an interrupt line is optional, but highly recommended to ensure proper and efficient readout of the
sensor data.
The pull-up resistors R1 & R2 of the I2C bus have to be set in a way to keep the rise- and fall time specification
of the interface bus parameters (see specification section) with the parasitic capacitive load of the actual
setup.
The serial resistances R between SDA /SCL & Pull up R1/R2 may be used to avoid reflections on longer bus lines
causing ground bouncing on sensor side and communication issues.
The series resistance R between and the SCL µC pin and the pull up resistor R2 together with the capacitance
C2 to ground may provide additional EMC filtering if required.
Please note: too small resistive values for R1/2 have to be prevented to avoid unnecessary power consumption
during interface transmissions, especially for low-power applications. The additional capacitor C2 on the SCL
line will limit the maximum possible bitrate on the bus.
Figure 6 Application Circuit with external Power Supply and µC
For additional EMC precaution in harsh environments, C1 may be implemented by two 100 nF capacitors in
parallel, which should be already given by CBuf near the µC and/or power supply.

3.1 Absolute Maximum Ratings
Attention: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to
the device. This is a stress rating only and functional operation of the device at these or any other
conditions above those indicated in the operational sections of this specification is not implied.
Furthermore, only single error cases are assumed. More than one stress/error case may also
damage the device.
Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
During absolute maximum rating overload conditions the voltage on VDD pins with respect to ground
(VSS) must not exceed the values defined by the absolute maximum ratings.

3D Magnetic Sensor
Specification
To provide these ultra low power consumption figures, the chip does not use a classic (and current
consuming) reset concept. The implemented reset focus is on ensuring a proper supply for the ADC operation
only (so it inhibits the ADC reliably until the sensor supply is high enough). Thus, the sensor rely on a proper
supply ramp including IDD-PUP current consumption during power-on to ensure it is initialized correctly. The I2C
reset feature of the sensor shall be used by the µC after power-up. If supply monitoring is used in the system
(e.g. brown-out detector etc.) it is also recommended to use the I2C reset of the sensor upon events detected
by this monitor.

TLV493D-A1B6
3D Magnetic Sensor
Interface and Timing Description
Managing correct sensor read outs by the µC:
This sensor does not incorporate shadow-buffers for readout. Thus, it is mandatory to read the sensor data
not during a running conversion to avoid corrupted reads. Ideally, the /INT feature is enabled together with
the low-power or ultra-low power mode and the µC reads the data after the /INT pulse was asserted by the
sensor. Furthermore, the readout needs to be finished before a new conversion is started and the /INT will be
asserted again (if the readout is finished 1 ms before a new /INT pulse, this will be sufficient).
Conversion register value to magnetic field and temperature value:
The conversion is realized by the two’s complement. Please use following table for transformation:
Example for 12Bit read out: 1111 0000 1111: -2048 + 1024 + 512 + 256 + 0 + 0 + 0 + 0 + 8 + 4 + 2 +1 = -241 LSB
Calculation to mT: -241 LSB * 0.098 mT/LSB = -23.6 mT
For further information and a detailed I2C bitmap please refer to user manual.
