The ZXCT1008Q 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. The ability to withstand high voltage transients and reverse polarity connection makes this part very suitable for automotive and other transient rich environment.
The ZXCT1008Q has been qualified to AEC-Q100 Grade 1 and is Automotive Grade supporting PPAPs.
