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 supervisor RESET delay 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
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.
