The XC6121D545ER-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 includes an EN/ENB pin for controlling the watchdog function, which can be set to off while maintaining voltage detection capabilities. The XC6121D545ER-G 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 across a temperature range of -40°C to +85°C and is available in SOT-25 and USP-6C packages, both compliant with EU RoHS standards. This product is suitable for applications such as microprocessor watchdog monitoring, memory battery backup circuits, system power-on reset circuits, and power failure detection.
