Programmable Watchdog Timer Supervisor IC with Open-Drain Reset Output for Reliable System Monitoring
The STWD100NYWY3F is a compact watchdog timer supervisor designed to monitor system activity and ensure reliable operation of microcontrollers and embedded processors. Developed by STMicroelectronics, this device detects system malfunctions caused by software errors or unexpected processor lockups and automatically generates a reset signal to restore normal operation.
The watchdog timer requires periodic trigger pulses from the microcontroller. If the expected signal is not received within the defined timeout period, the device asserts a reset through its open-drain output. This feature ensures system recovery and improves overall reliability in embedded systems. Packaged in a small SOT-23-5 form factor, the STWD100NYWY3F is well suited for industrial electronics, consumer devices, IoT hardware, and other applications requiring robust system supervision.
