The exposed thermal pad should be soldered to a ground-plane copper pour to keep junction temperature within the -40°C to 125°C range under continuous operation. ## Compliance documentation ROHS3 compliant.","metaTitle":"TPS3430WDRCR Watchdog Circuit, 10 µA, 1.6-6.5V, 10-VSON","metaDescription":"Active TPS3430WDRCR watchdog IC from TI. 10 µA supply, 1.6-6.5 V range, -40 to 125°C.
