AUTOMOTIVE HIGH-SIDE CURRENT MONITOR
ZXCT1008
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
environments.
