ZXCT1011

High-side low drift current monitor

Description

The ZXCT1011 is a high side current sense monitor. Using this type of device eliminates the need

to disrupt the ground plane when sensing a load current.

The ZXCT1011 takes the 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.

A current reference resistor, external to the IC, results in an improved temperature coefficient

compared to the ZXCT1009.

The wide input voltage range of 20V down to as low as 2.5V make it suitable for a range of

applications. With a minimum operating current of just 4uA, combined with its SOT23-5 package

make it suitable for portable battery equipment too.
