The STM6821RWY6F is a 5-pin supervisor IC designed for precision voltage monitoring of power supplies at levels of 5V, 3.3V, 3V, or 2.5V. It features both active low and active high reset outputs, which can be configured as push-pull or open-drain. The device includes a watchdog timer with a typical timeout period of 1.6 seconds and a manual reset input. It operates with a low supply current of approximately 3 ¬µA and guarantees reset assertion down to a supply voltage of 1.0V. The STM6821RWY6F is rated for an industrial temperature range of -40 to +85 ¬8C and is compliant with RoHS directives, ensuring lead-free components. This product is suitable for applications requiring reliable power supply monitoring and system reset functionality.
