Description
IP5389 is a power management SOC that
integrates QC2.0 / QC3.0 / QC3+ output fast
charging protocol, AFC/FCP/SCP/ VOOC input
and output fast charging protocol, USB C
PD2.0/PD3.0 input and output fast charging
protocol and PPS output protocol, BC1.2/iPhone
protocol, synchronous bi-directional buck-boost
converter, lithium battery charging management
and battery power indicator, providing a complete
power solution for fast charging mobile power
supplies. It can support four USB ports such as
two USB A ports, one USB C port and one USB B
port (lightning port or USB C port)at the same
time and fast charging when any USB port is
connected alone. When two or more output ports
are used at the same time, every port’s output
voltage is 5V.
Due to the high integration of IP5389, only
one inductor is needed to realize the bidirectional
buck-boost function. Only a few peripheral
components are needed in the application, which
effectively reduces the size of the overall solution
and reduces the BOM cost.
IP5389 supports 2/3/4/5 series batteries and
the synchronous switch buck-boost system can
provide a maximum output capacity of 100W.
When there is no load, it automatically enters the
dormant state.
IP5389 synchronous switch charging system
provides up to 8.0A charging current. The built-in
IC temperature, battery temperature and input
voltage control loop intelligently adjust the
charging current.
IP5389 built-in 14-bit ADC can accurately
measure battery voltage and current. Built-in
power calculation method can accurately obtain
battery power information. The battery power
curve can be customized to accurately display the
battery power.
IP5389 supports 4-LED power display,
supports 88, 188 and other nixie tube power
display; supports lighting function; supports keys.
