MICROPOWER FIXED GAIN OF 50 CURRENT MONITOR Description The ZXCT1023 is a precision high-side current sense monitor. Using this type of device eliminates the need to disrupt the ground plane when sensing a load current. The ZXCT1023 has a fixed internal gain of 50 and the only external ponent required is the external current sense resistor; this bined with its 1.2mm x 1.8mm TDFN package more than quarters the solution size of the ZXCT1010. The wide input voltage range of 20V down to as low as 2.5V makes it suitable for a range of applications. The bination of operation down to 2.5V and just 3.5µA quiescent current makes it ideal for single cell Li-Ion/polymer battery charge/discharge measurement applications.
