STMicroelectronics 5-Pin Surface Mount Watchdog Timer SOT-23 Package STWD100NYWY3F

STMicroelectronics STWD100NYWY3F is a 5-pin watchdog timer integrated circuit in a SOT-23 surface mount package. It is designed to monitor microprocessor operation and prevent system malfunctions by generating a reset or processor interrupt if the timer is not regularly cleared by the host system. This watchdog timer operates with a wide supply voltage range of 2.7V to 5.5V and supports a broad temperature range from -40°C to 125°C, making it suitable for industrial and embedded electronics applications requiring robust system monitoring.

The device's single internal timer counts down until cleared and if not reset within the timeout period, it triggers an output event to signal system failure. Its compact form factor with dimensions of 2.9mm length and 1.05mm height in the SOT-23 package allows space-efficient PCB designs. This watch dog timer has a 5-pin configuration optimized for surface mount technology, supporting automated manufacturing processes.

It does not carry any automotive standards but provides reliable protection for systems where hardware or software faults can cause critical failures. Typical applications include industrial controllers, embedded systems, and other electronics where continuous operation is vital.

Operates from 2.7V to 5.5V supply voltage. Single internal timer for watchdog functionality. 5-pin SOT-23 surface mount package. Temperature operating range from -40°C to 125°C. Compact and efficient footprint for embedded electronics.

Generates processor reset or interrupt signal on timeout. No automotive certifications included.

This component is ideal for professionals designing embedded or industrial electronics requiring a trusted watchdog timer solution. Explore more products in the Watchdog Timer category at EnvMart.
