ZXCT1009T8TA

Current Regulation/Management Overview

The ZXCT1009T8TA is a high-side current sense monitor manufactured by Diodes Incorporated. It translates the voltage developed across a current shunt resistor into a proportional output current, eliminating the need to disrupt ground planes during load current sensing. The device operates within a supply voltage range of 2.5V to 20V and supports a maximum sense voltage of 2.5V. It features a typical accuracy of 1% and a quiescent current of 4μA. Qualified under AEC-Q100 standards, it is designed for automotive applications and is available in SOT23 and SM8 packages.
