The TPS3850-Q1 combines a precision voltage supervisor with a programmable windowwatchdog timer. The TPS3850-Q1 window comparator achieves 0.8% accuracy (–40°C to +125°C) for bothovervoltage (VIT+(OV)) and undervoltage (VIT–(UV))thresholds. The TPS3850-Q1 also includes accurate hysteresis on both thresholds, making the deviceideal for use with tight tolerance systems. The supervisor RESET delay canbe set by factory-programmed default delay settings, or programmed by an external capacitor. Thefactory-programmed RESET delay features a 15% accuracy, high-precision delaytiming.
The TPS3850-Q1 includes a programmable window watchdog timer for a wide variety ofapplications. The dedicated watchdog output (WDO) enables increasedresolution to help determine the nature of fault conditions. The window watchdog timeouts can beset by factory-programmed default delay settings, or programmed by an external capacitor. Thewatchdog can be disabled via logic pins to avoid undesired watchdog timeouts during the developmentprocess.
The TPS3850-Q1 is available in a small 3.00-mm ×
3.00-mm, 10-pin VSON package. The TPS3850-Q1 features wettable flanks for easy opticalinspection.
