The SP691A/693A/800L/800M offers plete µP monitoring and watchdog functions. The SP691A/693A/800L/800M is ideal for a low-cost battery management solution and is well suited for portable, battery-powered applications with its supply current of 35µA. The 6ns chip-enable propagation delay, the 25m A current output in battery-backup mode, and the 250m A current output in standard operation also makes the SP691A/693A/800L/800M suitable for larger scale, high-performance equipment.
