The TPS35-Q1 is an ultra-low power consumption (250 nA typical) device offering a precision voltage supervisor with a programmable timeout watchdog timer. The TPS35-Q1 supports wide threshold levels for undervoltage supervision with 1.2% accuracy across the specified temperature range.

The TPS35-Q1 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, independent WDO pin option.

The RESET or 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 supervisor or watchdog fault is cleared.

The TPS35-Q1 provides a performance upgrade alternative to TPS3851-Q1 device family. The TPS35-Q1 is available in a small 8-pin SOT-23 package.
