TPS3850/TPS3851 Precision Voltage Supervisors

Texas Instruments TPS3850/TPS3851 Precision Voltage Supervisors combine a precision voltage supervisor with a programmable window watchdog timer. The TPS3850/TPS3851 window comparator achieves 0.8% accuracy (–40°C to +125°C) for both overvoltage (VIT+(OV)) and undervoltage (VIT–(UV)) thresholds. The TPS3850/TPS3851 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 factory-programmed default delay settings, or programmed by an external capacitor. The factory-programmed RESET delay features a 15% accuracy, high-precision delay timing. The TPS3850/TPS3851 includes a programmable window watchdog timer for a wide variety of applications. The dedicated watchdog output (WDO) enables increased resolution to help determine the nature of fault conditions. The TPS3850-Q1 devices are AEC-Q100 qualified for automotive applications.
