MPS MEZS7-1SSAPowerBank Manual

DESCRIPTION
The MEZS7-1SSAPowerBank is a complete
power bank solution module using the MP2632,
which includes a buck charger with BC1.2
detection, integrated boost with two separate
outputs, and a 4-LED indicator for battery state
of charge.
The solution module uses a form-fitting board
and supports two operating modes — charge
mode and boost mode — to allow management
of the system and battery power based on the
state of the input.
When a 5V USB input power is present, the
board charges a single-cell battery with a max
charge current of 3A. In the absence of an input
source, the solution module switches to boost
mode through the PB pin to power the USB
type-A output from the battery with up to 3A of
current.
The solution module provides four LED drivers
to achieve the voltage based fuel gauge
indication and distinguish charge mode from
boost mode.
To guarantee safe operation, the solution
module offers input over-voltage protection,
battery over-voltage
shutdown, battery temperature monitoring, and
a timer to prevent prolonged charging of a dead
battery.
