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 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.
