This product is a high side current sense monitor that can convert the high side voltage generated across a current shunt resistor 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 2.5V to as low as 2.5V makes it suitable for a range of applications. A minimum operating current of just 4µA, combined with its SOT23 package, makes it a unique solution, suitable for portable battery equipment.
The ZXCT1009 is a high-side current sense monitor designed to eliminate the need to disrupt ground planes when sensing load currents. It translates a high-side voltage developed across a current shunt resistor into a proportional output current, which can then be scaled by an external resistor into a ground-referenced voltage.
Key features include a wide input voltage range from 2.5V to 20V and a minimum operating current of just 4µA, making it suitable for portable battery equipment. The device is available in SOT23 and SM8+ packages.
