The TPS35-Q1 is an ultra-low power consumption (250 nA typical) device offering a precision voltage supervisor with a programmable 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 watchdog timer with a host of features for a wide variety of applications. The 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 feature can be enabled or disabled using a dedicated pin or combination of timer extension pins. The device also offers start-up delay options to disable watchdog monitoring for fixed time immediately after host power up or a RESET event. The TPS35-Q1 offers a pinout option with an independent WDO pin. This helps determine the nature of the fault condition.
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 is available in a small 8-pin SOT23 package.
