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.
