Texas Instruments TPS3436-Q1 Precision Window-Watchdog Timer is an ultra-low power consumption (250nA typical) device offering a programmable window watchdog timer. The TPS3436-Q1 provides 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 and startup delay.
The 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 watchdog fault is cleared. The TPS3436-Q1 provides a performance upgrade alternative to the TPS3430-Q1 device family. The Texas Instruments TPS3436-Q1 is available in a small 8-pin SOT-23 package.
