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.
The separate supply pin (VCC) allows the device to continue functioning under short circuit conditions, giving an end stop voltage at the output.
For automotive applications the ZXCT1081 has a 60V transient capability and ambient temperature range of -40°C to 125°C.
