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.
