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

component required is the external current sense resistor; this

combined 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 combination 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.
