ZXCT1008
INCREASED AMBIENT TEMPERATURE HIGH-SIDE CURRENT MONITOR
Description
The ZXCT1008 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.
