HIGH VOLTAGE HIGH-SIDE CURRENT MONITOR

Description

The ZXCT1081 is a high side current sense monitor with a

gain of 10 and a voltage output. Using this device

eliminates the need to disrupt the ground plane when

sensing a load current.

The wide input voltage range of 40V down to as low as 3V

make it suitable for a range of applications; including

systems operating from industrial 24-28V rails and power

supplies.
