Texas Instruments TPS3435/TPS3435-Q1 Nano Timeout Watchdog Timers
Texas Instruments TPS3435/TPS3435-Q1 Nano IQ Precision Timeout Watchdog Timer is a 250nA (typical) ultra-low power consumption device with a programmable timeout watchdog timer. This watchdog timer can be factory-programmed or user-programmed using an external capacitor, and the value can be changed by using a combination of logic pins. The TPS3435/TPS3435-Q1 timer offers a high-accuracy timeout watchdog timer with a host of features for various applications. This timer is available in a small 6-pin WSON and 8-pin SOT23 package. The TPS3435/TPS3435-Q1 timer operates at -40°C to 125°C temperature range. This timeout watchdog timer is ideal for robot servo drives, mixed module signals, HVAC controllers, electricity meters, infusion pumps, and surgical equipment.
