The ZXCT1012 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 ZXCT1012 takes the voltage developed across a small value resistor and translates it into a proportional output current. A user defined output resistor scales the output current into a ground referenced voltage.
The ZXCT1012 has the accuracy specification of the ZXCT1010 but in TSOT25.
A minimum operating current of just 3.5µA, combined with its TSOT25 package make it suitable for portable battery equipment where size and current consumption are critical.
The wide input voltage range down to as low as 2.5V make it suitable for a wide range of applications requiring direct operation from a battery.
