TPS3851 Description
The TPS3851 bines a precision voltage supervisor with a programmable watchdog timer. The TPS3851 parator achieves a 0.8% accuracy ( 40°C to +125°C) for the undervoltage (VITN) threshold. The TPS3851 also includes accurate hysteresis on the undervoltage threshold making the device ideal for use with tight tolerance systems.
