DESCRIPTION
The SP691A/693A/800L/800M is a microprocessor ( μ P) supervisory circuit that integrates
a myriad of components involved in discrete solutions to monitor power-supply and
battery-control functions in μ P and digital systems. The SP691A/693A/800L/800M offers
complete μ P 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 35 μ A. 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.
