Overview
ZXCT1009 HIGH-SIDE CURRENT MONITOR DESCRIPTION The ZXCT1009 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.
A minimum operating current of just 4µA, combined with its SOT23 package make it a unique solution, suitable for portable battery equipment.
FEATURES • • • • • • • Low cost, accurate high-side current sensing.
