STMicroelectronics 5-Pin Surface Mount Watchdog Timer SOT-23, 2.7V to 5.5V, -40°C to 125°C STWD100YNPWY3F

STMicroelectronics STWD100YNPWY3F 5-Pin Surface Mount Watchdog Timer in a SOT-23 package offers robust timing control and system monitoring to prevent system failures in electronic and semiconductor applications. It supports a supply voltage range of 2.7V to 5.5V, making it compatible with a wide range of embedded system power designs.

The device features a single internal Watchdog Timer which is periodically cleared during normal operation to avoid unwanted resets. If the system fails to clear the timer within the designated timeout period, the watchdog output asserts a processor interrupt or reset signal, thereby protecting against software or hardware malfunctions.

Designed for temperatures from -40°C up to 125°C and conforming to automotive standard AEC-Q100, this timer is ideal for automotive electronics, industrial automation, and other harsh environment applications requiring high reliability.

Its small footprint with a 3mm length and 1.3mm height allows efficient use in densely packed PCB designs, especially where space savings and surface mount technology are critical.

Single internal timer to monitor system health and generate reset signals. Compact surface mount SOT-23 package for space-efficient PCB integration. Wide operating voltage range (2.7V to 5.5V) supports versatile application environments.

Temperature tolerance from -40°C to 125°C for rugged and automotive use. Automotive standard AEC-Q100 certification ensures industrial-grade quality. Protects embedded systems from software and hardware failures via periodic reset control.

Easy integration into clock, timing, and frequency IC circuit systems.

This watchful timer is suited for industrial, automotive, and electronic component manufacturing sectors requiring fail-safe operation and reliability. EnvMart offers this STMicroelectronics model for advanced electronics design and manufacturing implementations.
