ZXCT1021  
ZXCT1022  
LOW OFFSET HIGH-SIDE CURRENT MONITOR  
DESCRIPTION  
APPLICATIONS  
The ZXCT1021/1022 are precision high side current  
sense monitors. Using this type of device eliminates  
the need to disrupt the ground plane when sensing a  
load current.

DC Motor control  
The ZXCT1021 provides a fixed gain of 10 while the  
ZXCT1022 has a gain of 100, for applications where  
minimal sense voltage is required.  
Over current monitor  
Power Management  
Level translating  
The very low offset voltage enables a typical accuracy  
of 2% for sense voltages of only 10mV, giving better  
tolerances for small sense resistors necessary at  
higher currents.  
Programmable current source  
The wide input voltage range of 20V down to as low as  
2.5V make it suitable for a range of applications. With a  
minimum operating current of just 25µA, combined  
with its SOT23-5 package make it suitable for portable  
battery equipment too.

Application Information  
The devices have fixed dc voltage gains of 10 and 100, no external scaling resistors are required for the output.  
Output voltage is simply defined as:  
Vout = gain x Vsense (V)  
Where Vsense = Vin - VLoad  
PCB trace shunt resistor for low cost solution.  
The figure below shows a PCB layout suggestion for a low cost solution where a PCB resistive trace in  
replacement for a conventional shunt resistor, can be used. The resistor section is 25mm x 0.25mm giving  
approximately 150mΩ using 1 oz copper. Smaller resistances can be used if required.  
GND  
Load  
Total circuit solution: 1 component. Shows area of 150mΩ sense resistor  
compared to SOT23 package.  
Practical tolerance of the PCB resistor will be around 5% depending on  
manufacturing methods.
