Texas Instruments TPS35/TPS35-Q1 Precision Voltage Supervisors are an ultra-low power consumption (250nA typical) device offering a precision voltage supervisor with a programmable timeout watchdog timer. The TPS35/TPS35-Q1 supports wide threshold levels for undervoltage supervision with 1.2% accuracy across the specified temperature range.
The TPS35/TPS35-Q1 offers a high-accuracy timeout watchdog timer with a host of features for various 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, startup delay, and 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/TPS35-Q1 provides a performance upgrade alternative to the TPS3851 device family. The TPS35/TPS35-Q1 is available in a small 6-pin WSON and 8-pin SOT-23 package. The Texas Instruments TPS35-Q1 devices are AEC-Q100 qualified for automotive applications.
