The XC6121E442MR-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 disabled while keeping the voltage detection active. 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 is suitable for various applications, including microprocessor watchdog monitoring, memory battery backup circuits, and system power-on reset circuits. The XC6121E442MR-G operates over a temperature range of -40¬8C to +85¬8C and is available in SOT-25 and USP-6C packages, compliant with EU RoHS standards.
