CAT812TTBI-GT3

Supervisors Overview

The CAT812TTBI-GT3 is a single-channel voltage supervisor IC from onsemi, designed for microprocessor power supply monitoring. It operates within a supply voltage range of 1.2 V to 5.5 V and features a fixed overvoltage threshold of 4 V. The device provides an active high reset signal with a push-pull output type and a reset delay time of 20 us. It consumes a typical operating supply current of 6 uA and supports manual reset functionality. The component is housed in a SOT-143-4 package and functions reliably across an industrial temperature range of -40 C to +85 C.
