Nano-quiescent-current precision timeout watchdog timer | DDF | 8 | -40 to 125

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 to TPS3431

device family. The TPS3435 is available in a small 6-pin WSON and 8-pin SOT-23 package.
