Torex Semiconductor, Ltd. Supervisors XC6121A438ER-G

The XC6121A438ER-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, adjustable in 0.1V increments, and features an operating voltage range of 1.0V to 6.0V. The device includes a built-in delay circuit, eliminating the need for external components to manage release delay times, which can be set to various durations from 3.13ms to 400ms. This supervisor integrates an N-channel open drain output and offers six selectable watchdog timeout periods ranging from 50ms to 1.6s. The EN/ENB pin allows for control over the watchdog function, which can be disabled while keeping the voltage detection active. The XC6121A438ER-G is suitable for applications such as microprocessor monitoring, memory battery backup, system power-on reset, and power failure detection. It is available in environmentally friendly packages, compliant with EU RoHS standards, and operates effectively in ambient temperatures from -40¬8C to +85¬8C.
