MPS SharedPowerBank MEZS7 Quick Start Manual

DESCRIPTION
The MEZS7-SharedPowerBank is a complete
solution module using the MP2696A buck
charger with boost output, LED state-of-charge
indicator, and an MCU to achieve a turn-key
solution for shared power bank applications.
The MP2696A is a highly integrated, flexible,
switch-mode battery charge management and
system power path management device.
The MP2696A has three operation modes:
charge mode, boost mode, and sleep mode.
In charge mode, the solution module achieves
up to 3.6A of charge current from a 5V micro
USB input source.
In boost mode, the solution module delivers up
to 3.6A to a regulated 5V USB-A output for
charging external
smartphones. All the parameters and controls
can be easily accessed via the I
