ZXCT1008QFTA

ZXCT1008QFTA 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 makes 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. Applications include automotive current measurements, automotive DC motor stall detections, and overcurrent monitors.
