The UCC2946TPWRQ1 from Texas Instruments is an integrated circuit designed for microprocessor supervision. It offers essential reset and watchdog timer functions, crucial for system stability.
This device is rated for automotive applications and operates within a voltage range of 2.1V to 5.5V. It features a typical reset threshold voltage of 1.235V with 2% accuracy. The supervisor monitors a single supply and provides an active-low, push-pull reset output. A watchdog timer function is also included, with a programmable period, to ensure the microprocessor is operating correctly.
The UCC2946TPWRQ1 is supplied in an 8-TSSOP package, suitable for surface mounting. It operates across a wide temperature range of -40°C to 105°C. The device is designed to be resistant to glitches on the VDD line, enhancing its reliability in demanding environments. Its low quiescent current of 0.012mA makes it suitable for power-sensitive applications.
Key features include a programmable reset threshold and period, along with a programmable watchdog timer. The input voltage can be as low as 2V, and the reset is valid down to 1V. The maximum input current is 18µA.
