TPS3850-Q1에 대한 설명
The TPS3850-Q1 combines a precision voltage supervisor with a programmable window watchdog timer. The TPS3850-Q1 window comparator achieves 0.8% accuracy (–40°C to +125°C) for both overvoltage (VIT+(OV)) and undervoltage (VIT–(UV)) thresholds on the SENSE pin. The TPS3850-Q1 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 9.5% accuracy, high-precision delay timing.
The TPS3850-Q1 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 window watchdog timeouts can be set by factory-programmed default delay settings, or programmed by an external capacitor. The watchdog can be disabled via logic pins to avoid undesired watchdog timeouts during the development process.
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 optical inspection.
