Nisshinbo Micro Devices Inc. Supervisors R5109G271C-TR-FE

The R5109G271C-TR-FE is a microprocessor supervisory circuit designed for high accuracy and low supply current applications. It operates within a voltage range of 0.9V to 6.0V and features a built-in delay circuit and watchdog timer. The voltage detector has a fixed internal threshold accuracy of ±1.0% and can be set between 1.5V and 5.5V in 0.1V steps. The power-on reset delay time is adjustable with an external capacitor, typically around 370ms with a 0.1µF capacitor, and has an accuracy of ±16%. The watchdog timer can supervise two different clock inputs and has a timeout period that can also be set with an external capacitor, typically around 310ms, with an accuracy of ±33%. The device includes an inhibit function to stop the watchdog timer and offers selectable output types, either Nch open-drain or CMOS. The R5109G is packaged in an SSOP-8G format, making it suitable for various microprocessor supervisory applications.
