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.
