The XC6121F644ER-G is a voltage detector with a watchdog function designed for low current consumption and high precision. 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 supports six selectable watchdog timeout periods ranging from 50ms to 1.6s and offers five release delay times from 3.13ms to 400ms. This product is suitable for applications such as microprocessor watchdog monitoring, memory battery backup circuits, system power-on reset circuits, and power failure detection. The XC6121F644ER-G operates within an ambient temperature range of -40,ÑÉ to +85,ÑÉ and is available in SOT-25 and USP-6C packages, both of which are compliant with EU RoHS standards. The output configuration is an N-channel open drain, and the device includes an EN/ENB pin for controlling the watchdog function.
