Low Power Microprocessor Supervisory
with Battery Switch-Over
SP691A/693A/800L/800M
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.
