ZXCT1011
High-side low drift current monitor
Description
The ZXCT1011 is a high side current sense monitor. Using this type of device eliminates the need
to disrupt the ground plane when sensing a load current.
The ZXCT1011 takes the 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.
A current reference resistor, external to the IC, results in an improved temperature coefficient
compared to the ZXCT1009.
The wide input voltage range of 20V down to as low as 2.5V make it suitable for a range of
applications. With a minimum operating current of just 4uA, combined with its SOT23-5 package
make it suitable for portable battery equipment too.
