Description

The SP691A/693A/800L/800M is a microprocessor (µP) supervisory circuit that integrates a myriad of components involved in discrete solutions to monitor power-supply and battery-control functions in µP and digital systems. The SP691A/693A/800L/800M offers complete 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 25mA current output in battery-backup mode, and the 250mA current output in standard operation also makes the  SP691A/693A/800L/800M  suitable for larger scale, high-performance equipment.
