Texas Instruments TPS36-Q1 Ultra-Low Power Precision Supervisor consumes 250nA (typical) and offers a precision voltage supervisor with a programmable window watchdog timer. The TPS36-Q1 supports wide threshold levels for undervoltage supervision with 1.2% accuracy across the specified temperature range. The TPS36-Q1 offers a high-accuracy window watchdog timer with a host of features for various applications. The close window timer can be factory-programmed or user-programmed using an external capacitor. The open window-to-close window ratio can be changed on-the-fly using a combination of logic pins. The watchdog also offers unique features such as enable-disable, startup delay, and independent WDO pin option.
The RESET or WDO delay can be set by factory-programmed default delay settings or programmed by an external capacitor. The device also offers a latched output operation where the output is latched until the supervisor or watchdog fault is cleared. The Texas Instruments TPS36-Q1 provides a performance upgrade alternative to the TPS3852-Q1 device family. The TPS36-Q1 is available in a small 8-pin SOT-23 package.
