DESCRIPTION

The

MPQ5480

is

a

monolithic

power

management solution for wearable device.

It contains a USB compatible, constant current/

constant voltage charger along with a high

efficiency synchronous step down regulator.

The MPQ5480 also features cell protection and

a separate power switch for powering additional

power devices.

The hysteresis control scheme provides fast

transient response and eases loop stabilization.

Fault condition protection includes cycle by

cycle current limiting, output short protection

and thermal shutdown.

The MPQ5480 requires a minimum number of

external components and is available in a

WLCSP-16 (1.7mmx1.7mm) package.
