STWD100NYWY3F-STMICROELECTRONICS-Watchdog Timer, 2.7 V to 5.5 V Supply, 3.4 ms/6.3 ms/102 ms/1.6 s, Active-Low, Open-Drain, SOT-23-5

The STWD100NYWY3F by STMicroelectronics is a Watchdog Timer (WDT) designed to enhance the reliability and safety of electronic systems by monitoring their proper operation. Operating within a supply voltage range of 2.7V to 5.5V, this watchdog timer is suitable for various power supply configurations in electronic applications. The timer offers multiple selectable timeout periods of 3.4ms, 6.3ms, 102ms, and 1.6s, allowing flexibility in system monitoring based on specific requirements.

Featuring an active-low, open-drain output configuration, the STWD100NYWY3F provides a signal that goes low when the watchdog timer expires, signaling a potential issue in the system. The device is packaged in a compact SOT-23-5 package, offering five pins for straightforward integration into electronic circuit designs. With its functionality and configuration options, this watchdog timer is commonly employed in applications such as embedded systems and microcontroller-based designs, providing an additional layer of protection by ensuring proper system functioning.
