The TPS3436 is an ultra-low-power consumption (250nA typical) device offering a programmable window watchdog timer.
The TPS3436 offers a high accuracy window watchdog timer with host of features for a wide variety of applications. The close window timer can be factory programmed or user programmed using an external capacitor. The open window to close window ratio can change unpremeditatedly using a combination of logic pins. The watchdog also offers unique features such as enable-disable, start-up 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 provides a performance upgrade alternative to the TPS3430 device family. The TPS3436 is available in small 6-pin WSON and 5-pin and 8-pin SOT-23 package.
