TPS3851/TPS3851-Q1 Precision Voltage Supervisors

Texas Instruments TPS3851/TPS3851-Q1 Precision Voltage Supervisors combine 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 and high-precision delay timing. The TPS3851/TPS3851-Q1 includes a programmable watchdog timer for various applications. The dedicated watchdog output (WDO) enables increased resolution to help determine the nature of fault conditions. Watchdog timeouts can be programmed either by an external capacitor or factory-programmed default delay settings. The TPS3851-Q1 devices are AEC-Q100 qualified for automotive applications.
