| Watchdog Timer |
The Texas Instruments TPS3431SDRBR is a standard programmable watchdog timer with an enable feature, suitable for a variety of applications requiring robust system supervision. This IC offers a programmable watchdog timeout, with a typical WDI of 0.2 seconds, and a reset threshold accuracy of ±2.5% at 25°C. It supports an input voltage range from 1.8V to 6.5V and consumes a low quiescent current of 10µA typical.
The TPS3431SDRBR features an active-low, open-drain reset output and includes an enable input (EN) and enable output (ENOUT). The device operates across a junction temperature range of -40°C to 125°C. It is available in a compact 3mm x 3mm, 8-pin VSON package, making it suitable for space-constrained designs. The watchdog disable feature provides added flexibility during system configuration or testing.
This watchdog timer is designed to monitor the proper functioning of microprocessors and other digital systems. If the system fails to periodically reset the watchdog timer, the TPS3431SDRBR will assert its reset output, helping to prevent system failures or data corruption. Its reliable performance and small footprint make it a valuable component in embedded systems, industrial controls, and automotive applications.
