Torex Semiconductor, Ltd. Supervisors XC6121E547MR-G

The XC6121E547MR-G is a voltage detector with a watchdog function designed for low current consumption applications. It operates within a voltage detection range of 1.6V to 5.0V, with fixed increments of 0.1V, and features a built-in delay circuit that eliminates the need for external components. The device provides an N-channel open drain output and includes an EN/ENB pin for controlling the watchdog function, which can be turned off while maintaining voltage detection capabilities. This supervisor IC supports six selectable watchdog timeout periods ranging from 50ms to 1.6s and offers five release delay times from 3.13ms to 400ms. It operates effectively within an ambient temperature range of -40,ÑÉ to +85,ÑÉ and is packaged in SOT-25 or USP-6C formats, compliant with EU RoHS standards. Typical applications include microprocessor monitoring, memory backup circuits, and power-on reset functions.
