Description
AI
The TPS3435 is an ultra-low power consumption (250nA typical) device offering a programmable timeout watchdog timer.
The TPS3435 offers a high accuracy timeout watchdog timer with a host of features for a wide variety of applications. The timeout watchdog timer can be factory programmed or user programmed using an external capacitor. The timer value can be changed on-the-fly 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 TPS3435 provides a performance upgrade alternative toTPS3431device family. The TPS3435 is available in a small 6-pin WSON and 8-pin SOT-23 package.
