STWD100NXWY3F ST Watchdog Timer | SOT-23-5 | 1.6s Timeout, 2.7-5.5V

Product Overview

The STWD100NXWY3F is a standalone watchdog timer from STMicroelectronics, designed to monitor system activity and reset the host microcontroller if it fails to strobe within a preset timeout period. Housed in a compact SOT-23-5 package, this device ensures reliable operation in safety-critical applications. It operates over a wide supply voltage range of 2.7V to 5.5V and offers a typical watchdog timeout of 1.6 seconds. The open-drain output (RST) asserts low when a timeout occurs, providing a clean reset signal. With ultra-low power consumption (typically 1.5µA), it is ideal for battery-powered and energy-efficient systems.
