STWD100NYWY3F - ST
The STWD100NYWY3F is an AEC-Q100 qualified automotive watchdog timer IC, ideal for safety-critical systems requiring reliable microcontroller supervision. Select this device when your design demands a simple, external watchdog independent of the MCU's internal timer. Its factory-programmed 1.12s minimum timeout and open-drain, active-low reset output ensure a fail-safe system reset if software hangs. This makes it perfect for automotive ECUs, ADAS subsystems, body control modules, and industrial controllers. The SOT-23-5 package saves board space, while the -40°C to +125°C operating range guarantees robust performance in harsh under-hood environments. Use it to enhance functional safety in any microcontroller-based design requiring a trusted external watchdog. In stock at HL Electronics – request a quote for fast delivery.
