Richtek RT6052 High-Side Measurement Current Shunt Monitor

Richtek RT6052 High-Side Measurement Current Shunt Monitor combines a current-sense amplifier, bandgap reference, and a comparator with latching output. The RT6052 ascertains drops across shunts within 2V to 80V common-mode voltages and supports a 100V/V output voltage scale.

The RT6052 monitor features a built-in open-drain comparator and internal reference providing a 0.6V threshold. External dividers set the current trip point. The comparator offers a latching capability that can be made easily by grounding (or leaving open) the RESET pin.

The Richtek RT6052 is enclosed in a small 8-pin MSOP package.
