Description

The TPS3852-Q1 is a precision voltage supervisor with an integrated window watchdog timer. The TPS3852-Q1 includes a precision undervoltage supervisor with an undervoltage threshold (VITN) that achieves 0.8% accuracy over the specified temperature range of –40°C to +125°C. In addition, the TPS3852-Q1 includes accurate hysteresis making the device ideal for use with tight tolerance systems. The supervisorRESETdelay features a 15% accuracy, high-precision delay timer. The TPS3852-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 watchdog timeouts can be programmed either by an external capacitor or by factory-programmed default delay settings. The watchdog can be disabled to avoid undesired watchdog timeouts during the development process. The TPS3852-Q1 is available in a small 3.00-mm × 3.00-mm, 8-pin VSON package. The TPS3852-Q1 features wettable flanks that allow for easy optical inspection. The TPS3852-Q1 is a precision voltage supervisor with an integrated window watchdog timer.
