The TPS3436-Q1 is an ultra-low power consumption (250 nA typical) device offering a programmable window watchdog timer.
The TPS3436-Q1 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 be changed on-the-fly using a combination of logic pins. The watchdog feature can be enabled or disabled using a dedicated pin or combination of ratio pins. The device also offers start-up delay options to disable watchdog monitoring for fixed time immediately after host power up.
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 is available in a small 8-pin SOT23 package.
