SBVS301A – OCTOBER 2016 – REVISED NOVEMBER 2016 TPS3850 Precision Voltage Supervisor with Programmable Window Watchdog Timer
1 Features 3 Description The TPS3850 combines a precision voltage
supervisor with a programmable window watchdog
timer. The TPS3850 window comparator achieves
0.8% accuracy (–40°C to +125°C) for both
overvoltage (VIT+(OV) and undervoltage (VIT–(UV)
thresholds. The TPS3850 also includes accurate
hysteresis on both thresholds, making the device
ideal for use with tight tolerance systems. The
supervisor RESET delay can be set by factoryprogrammed default delay settings, or programmed
by an external capacitor. The factory-programmed
RESET delay features a 15% accuracy, highprecision delay timing. 1 0.8% Voltage Threshold Accuracy
Precision Over-and Undervoltage Monitoring:
– Supports Common Rails from 0.9 V to 5.0 V
– ±4% and ±7% Fault Windows Available
– 0.5% Hysteresis
Factory-Programmed Precision Watchdog and …
