SEMICO NDUC TORS

DESCRIPTION

The ZXCT1009 is a high side current sense monitor.

Using this device eliminates the need to disrupt the

ground plane when sensing a load current.

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 4 A, combined with

its SOT23 package make it a unique solution for

portable battery equipment.
