ZXCT1081
Document number: DS32102 Rev. 1 - 2
Typical Application Circuit
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.
