Description
The ZXCT1107/09/10 are high side unipolar current sense
monitors. These devices eliminate the need to disrupt the
ground plane when sensing a load current.
The wide common-mode input voltage range and low
quiescent current coupled with SOT23 packages make
them suitable for a range of applications; including
adapters, automotive and system s operating from industrial
24V rails.
The device is line powered and as such doesn’t need a
separate supply rail.
Quiescent current is only 3µA thereby minimising current
sensing error. One external gain setting resistor increases
versatility by permitting wide gain ranges.
Features
• Wide supply and common-mode voltage range:
2.5V to 36V
• SOT23 packages
o 3-pin ZXCT1107/09
o 5-pin ZXCT1110
• Low quiescent current (3µA).
• Extended industrial temper ature range -40 to 125°C
• AEC-Q100 Grade1 Automotive qualified variants
Applications
• Automotive current measurement
• Industrial applications current measurement
• Battery management
• Over current monitor
• Power Management

OUT 11 1
1 3 Output pin. Current output.
S+ 3 2 4
This is the positive input of the current monitor and has a wide
common-mode input range. This also acts as the anal og supply and
provides power to internal circuitry. The current through this pin
varies with differential sense voltage.
S- 2 3 5
This is the negative input of the current monitor and has a wide
common-mode input range.
GND - - 2 Ground pin and substrate connection.
NC - - 1 No connection
Notes. 1. For the ZXCT1107 and ZXCT1109 pin 1 (OUT) acts as both the output pin and substra te con nection. This means tha t for the
ZXCT1107 and ZXCT1109 the minimum rail voltage that can be used is 2.5V + VOUT (see applications section for more details).

Operation above the absolute maximum rating may cause device failure. Operation at the absolute maximum ratings,
for extended periods, may reduce device reliability.

Application Information
Description
The current monitor ICs ZXCT1107, ZXCT1109 and ZXCT1110 all use a similar application circuit topology for high-side
current sensing, with small differences. The ZXCT1110 has a separate ground pin whereas the ZXCT1107 and ZXCT1109
do not. The use of ZXCT1110 allows reduct ion of the absolute current measurement error in some applications b y providing
a reduced output offset current. The ZXCT1107 provides a mirror image pin assignment of the ZXCT1109 to ease PCB
layout in very small equi pment designs.
The basic application circuit for each devic e is shown in Figure 1. Two external resistors are required. The resistor RSENSE
is connected in the path of the current to be monitored. T he resistor RGAIN converts the device output current to a voltage fo r
convenient processing by a further device, such as a comparator, amplifier or analog-to-digital converter within a
microcontroller system.
The current monitor output current is defined through the nominal transconductance of 4 m A/V.

OUT = 0.004 * VSENSE Amp Equation 1

Figure 1. Basic Application Circuit
Calculation of Resistor Values
In order to select RSENSE, a choice of sense voltage is requi red. This often invo lves a compromise between po wer efficiency
and accuracy for the given te mperature range. The resistor must be small enou gh to avoid excessive volt drop bet ween the
power supply and the load. However, the resistor must be large enough to avoid excessive current measurement error,
particularly random errors.
In a typical application, a digital system, perhaps a microcontroller, is set up to monitor the current. At a certain threshold
current level, ILOADT, the system is required to disconnect the load or report a fault. At this current level, the current
measurement error must be limited to a known value. The total percentage error comprises the inherent error in the
ZXCT1107/1109/1110 device and the tolerances of the two resistors RSENSE and RGAIN. The ZXCT1107/ZXCT1109
absolute error is shown in Table 1 with error limits drawn from the table of Electrical Characteristics above. T his error varies
with VSENSE.

Application Information (cont.)
The ZXCT1110 is hi ghly linear and has a tr ansconductance of 4mA/V ±1.8% and an out put of 40µA ±4µA at VSENSE=10mV.
The output current can therefore be calculated (Standar d International Units) as:
I
OUT = (40 +/-4)*10-6 + (VSENSE-0.01)*(0.004 +/- 0.000072) Amp
The worst-case current error is then
I
OUTERROR = IOUT – IOUTIDEAL = +/- { 4*10-6 + (VSENSE-0.01) * 0.000072 } Amp
or IOUTERROR = +/- { 3.28*10-6 + VSENSE * 0.000072 } A

Application Information (cont.)
Note that in order to avoid additional error, VSUPPLY must be at least 1.5V greater than VOUT. This margin depends on the
value of VSENSE. For VSENSE = 100mV, this margin can be reduced to 1.0V.
RSENSE is chosen based on the threshold VSENSET of sense voltage select ed as ab ove, for the chose n threshold l oad c urrent,

Design Example
A current monitor is required to provi de an output voltage of 2V ±6% when the load current of a 12V supply is 2A. Resistors
are available with 1% toler ance.
The sense and output resistors will contribute a total possib le error of 2%, so the ZXCT11xx error must not exce ed 4%. Fr om
Table 1, the error of ZXCT1107/1109 will be 3.4% if the sense voltage is 100mV. This satisfies the total error requirem ent of
6%.
Equation 4 gives

SENSE = 100mV/2A = 50mΩ
Equation 5 gives

RGAIN = = 5kΩ
A suitable preferred value is 5.1k. This gives a systematic error of +2%, which can be compensated elsewhere in the
system if desired. Figure 2 shows the resulting schematic.

Alternatively, the ZXCT1110 may be used with a reduced sense voltage if desired. From Equation 3, with =4%,

Equation 4 gives

A suitable preferred value is 20m. Then the sense voltage will be 2A * 20m = 40mV.

A suitable preferred value is 13k.
The alternative example circuit using the ZXCT1110 with a sense voltage of 40mV is shown in Figure 3, giving the required

Protection Against Load Short Circuit
In the event of a load short circuit or overload, a large proportion of the supply voltage may appear between the sense
terminals. The supply may be current limited, but there is normally a large reservoir capacitor which can deliver enough
energy to damage the ZXCT 11xx before the supply voltage falls to a safe level due to current limit activation.
The ZXCT11xx is rated for a maximum se nse voltage of +0.8V, but is safe if the input current is limited t o ±8.5mA. In Figure
4, the resistor RPROT limits the current and therefore protects the current monitor device against load short circuit without
introducing significant current measurement error.

Application Information (cont.)
Figure 4. Protection and EMC Filtering
EMC Susceptibility
In many applications, the circuit is required to operate in the presence of RF radiation. This radiation is coupled into the
circuit via the supply or load connections and will often cause significant bias shift due to rectification within the integrated
circuit. The bias shift may lead to erroneous operation of the integrate d circuit. In Figure 4, a low pass filter, RPROT and C1,
provides significant attenuatio n in the VHF and UHF regions. The value of C1 is recommended to be in the range of 10 pF to
47pF, leadless ceramic type.
PCB Layout Considerations
It is necessary to take into account a small volt drop in the PCB copper and solder joints to RSENSE. Such volt drops can
create noticeable error at currents of the order of 1A and greater. The PCB must be designed to provide the maximum
possible copper carrying current via the sense resistor, and the tr aces from the S+ and S- pins must be connected only to the
resistor pads. In this way, the effect of the copper is minimized.
If used, the capacitor C1 should be placed very close the input pins S+ an d S-.
Application: High Voltage Current Monitor
The schematic of Figure 5 shows how the current monitor may be used in a high voltage application such as a TV LED
backlight system. In this configuration the 500V PNP transistor Q1 drops a large proportion of the supply voltage. Diode D2
limits the differential input voltage to a safe level under overload conditions. The voltage across U1 is limited by the zener
diode D1. The output current of U1 is limite d to about 3mA by the D2. As RGAIN is typically a few k, the output voltage is
therefore limited to a few volts. An additional output clamping diode ma y be required for higher gains. R1 is chosen to give
a suitable bias current in D1 for the given supply voltage range.
