STWD100PYW83F ST Watchdog Timer | SOT-323-5 | 1.6s Timeout, 2.7-5.5V

Product Overview

The STWD100PYW83F 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-323-5 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 features a typical watchdog timeout of 1.6 seconds. The open-drain RST output is active low, providing a reset signal to the host. With low power consumption and high accuracy, the STWD100PYW83F is ideal for embedded systems requiring robust supervision.
