SBVS300 – NOVEMBER 2016 TPS3851 Precision Voltage Supervisor with Integrated Watchdog Timer
1 Features 3 Description The TPS3851 combines a precision voltage
supervisor with a programmable watchdog timer. The
TPS3851 comparator 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. The
supervisor RESET delay features a 15% accuracy,
high-precision delay timing. 1 0.8% Voltage Threshold Accuracy
Precision Undervoltage Monitoring:
– Supports Common Rails from 1.8 V to 5.0 V
– 4% and 7% Undervoltage Thresholds
Available
– 0.5% Hysteresis
Factory-Programmed Precision Watchdog and
Reset Timers: …
