The Texas Instruments TPS3431SDRBR is a supervisory circuit providing a single-channel programmable watchdog timer with an enable input. It is supplied in an 8-pin VSON package measuring 3mm square and 1mm high, and its product title gives a -40°C to 125°C operating range. The TPS3431SDRBR is a production part and is recorded as RoHS non-compliant.
A watchdog timer is a supervisory device the processor must keep resetting within a set interval; if the software hangs, misses its deadline, or falls into an unintended loop, the timeout expires and the watchdog asserts a reset that recovers the system with no human involvement. Making the timeout programmable lets one part cover boards whose boot and service intervals differ, and the enable input lets the watchdog be suspended during programming and debugging. The TPS3431SDRBR is used in industrial controllers and remote instrumentation, automotive electronic control units, communications and networking equipment, and any unattended system where sending a technician to power-cycle a hung board is expensive. Typical buyers are embedded designers building for functional safety and high availability.
Fusion’s in-house quality hubs and Prosemi testing facility are fully certified to meet critical industry standards for electronic component inspection and testing.
