The RTQ6050/RTQ6052 devices are high-side current-shunt monitors which contain a current-sense amplifier, bandgap reference, and a comparator with latching output. The RTQ6050/RTQ6052 senses drops across shunts at common-mode voltages from 2V to 80V. The RTQ6050/RTQ6052 series supports two output voltage scales : 20V/V, and 100V/V.

The RTQ6050 and RTQ6052 build in an open-drain comparator and internal reference providing a 0.6V threshold. External dividers set the current trip point. The comparator features a latching capability, that can be made easily by grounding (or leaving open) the RESET pin.

The RTQ6050/RTQ6052 is available in a small 8-pins MSOP package.
