DescriptionThe TPS3851-Q1 device combines a precision voltage supervisor with a programmablewatchdog timer. The TPS3851-Q1 comparator achieves a 0.8% accuracy (–40°C to +125°C) for theundervoltage (VITN) threshold. The TPS3851-Q1 also includes accuratehysteresis on the undervoltage threshold making the device ideal for use with tight tolerancesystems. The supervisor WDO) enables increasedresolution to help determine the nature of fault conditions. The watchdog timeouts can beprogrammed either by an external capacitor, or by factory-programmed default delay settings. Thewatchdog can be disabled via logic pins to avoid undesired watchdog timeouts during the developmentprocess.
The TPS3851-Q1 is available in a small 3.00-mm × 3.00-mm, 8-pin VSON package. TheTPS3851-Q1 features wettable flanks that allow for easy optical inspection.
