Charge

IP5328P integrated a constant current and constant voltage Li battery charging management system with

synchronous switch, adaptive to various charging voltage.

When the battery voltage is lower than 3V, trickle charging less than 200mA charging current is applied;

when the battery voltage is higher than 3V, enters constant current charging stage, the maximum charging current

at battery port is 5.0A; when the battery voltage is near the preset battery voltage, enters constant voltage

charging stage; when the charging current is less than 300mA and battery voltage is near the constant voltage

charging stage, the charging process is stopped. When the charging stage is accomplished, once the battery

voltage falls under 4.1V, battery charging stage will be restarted.

IP5328P adopted switch charging technology, switch frequency is 500kHz. During 5V input voltage, maximum

input power is 10W; During the fast charging state, maximum input power is 18W. The highest charging current is

up to 5.0A, charging efficiency can be up to 94%, such can reduce 3/4 charging time.

IP5328P will adjust charge current automatically applicable to adaptors with different load capacity.

IP5328P do not support charging the battery and phone at the same time, the output discharge port will be

close while charging the battery, in case the input high voltage will take damage on the device under charge.

Boost

IP5328P Integrated a synchronized switch converter which supports high voltage output, providing 5V~12V

output voltage output, load capacity can be: 5V/3.1A, 7V/2.4A, 9V/2.0A and 12V/1.5A. 375kHz switching frequency.

Internal soft start function. In avoid of large rush current causing device failure at start up stage, built-in

overcurrent, short circuit, overvoltage and over temperature protection function, make insurance of the stability

and reliability of power system.

Boost system output current can be auto-modulated according to the temperature, ensuring the IC is under

the preset temperature.

USB C

IP5328P integrated USB C DRP port, auto-switching the internal pull-up and pull-down circuit on CC1 and CC2

by distinguishing the role of the attached device. Support Try.SRC function, when the attached device is also DRP

device, IP5328P will supply power for the opposite device.

When worked as DFP, the output current can be set as three levels; when worked as UFP, the current

capability from the opposite device can be detected.
