Description

The ZXCT1080 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 60V down to as low as 3V make it suitable for a range of applications; including systems operating from industrial 24-28V rails and -48V rails.

Feature(s)

3V to 60V continuous high side voltage

Accurate high-side current sensing

-40 to 125°C temperature range

Output voltage scaling x10

4.5V to 12V V_CC range

Low quiescent current:

80μA supply pin

27μA IS+

SOT25 package

Application(s)

Industrial applications current measurement

Battery management

Over-current measurement

Power management

Automotive current measurement
