ZXCT1009Q

AUTOMOTIVE GRADE MICROPOWER CURRENT MONITOR

The ZXCT1009Q is a micropower high side current sense monitor.

This device eliminates the need to disrupt the ground plane when sensing a load current.

Pin Assignments

SOT23 Package Suffix - F

It takes a high side voltage developed across a current shunt resistor and translates it into a proportional output current. A user defined output resistor scales the output current into a ground-referenced voltage.

The wide input voltage range of 20V down to as low as 2.5V make it suitable for a range of applications. A minimum operating current of just 4µA, combined with a SOT23 package make it a unique solution for portable battery equipment.
