The STWD100NXWY3F is a watchdog timer circuit designed to prevent system failures caused by hardware and software errors. It features a typical current consumption of 13 ¬µA and offers selectable watchdog timeout periods of 3.4 ms, 6.3 ms, 102 ms, and 1.6 s. The device includes a watchdog input (WDI) for periodic resets and a watchdog output (WDO) that asserts an alert if the system fails to reset the timer. The STWD100NXWY3F operates over an extended temperature range of -40 to 125 ¬8C and is available in SOT23-5 packaging. It is automotive qualified, ensuring reliability in demanding applications. The device is suitable for various applications, including telecommunications, alarm systems, industrial equipment, networking, medical equipment, uninterruptible power supplies, and automotive systems. The enable pin (EN) allows for easy activation or deactivation of the watchdog functionality. ESD performance is rated at 2000 V for HBM and 1000 V for CDM, enhancing its robustness in sensitive environments.
