Bidirectional PD 100 watt mobile power solution based on Yingjixin IP5389-BZ chip design

Verified successfully November 27, 2021

Supports 2-5 string battery packs

Also supports lithium iron phosphate batteries (need to replace the resistor to set the battery type)

An electronic communication group: 232586710

The chip manual is available in the group file

9V ripple curve is about 16mV

Input and output power up to 100 watts

Notice! ! !

When the board is inputting and outputting high power, the current at the battery terminal is very large. Please pay attention to the battery selection.

The board does not have lithium battery protection and balancing circuits, and a protection board with balancing function needs to be used on the battery side.

The power MOS is BSC059N04LS6. This MOS has a small Ciss, high efficiency and low heat generation.

As the output switch MOS, any one with low internal resistance will do.

The inductor used is Sumida’s CDEP1411NP-100MC-95

IP5389 is an integrated 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 protocol, USB C PD3.0 PPS output protocol, compatible with BC1.2/Apple mobile phones, synchronous bidirectional buck-boost converter, lithium battery charging management, battery power indicator and other multi-functional power management SOC provide a complete power solution for fast charging mobile power supplies. It can support four USB ports, USB A .

IP5389's high integration level and rich functions require only one inductor to realize the bidirectional buck-boost function. Only a few peripheral components are needed during application, which effectively reduces the size of the overall solution and reduces the BOM cost.

IP5389 supports 2/3/4/5 cells in series, and the synchronous switching boost and buck system can provide a maximum output capacity of 60W. When no-load, it automatically enters sleep state.

IP5389's synchronous switching charging system provides up to 5.0A charging current. Built-in IC temperature, battery temperature and input voltage control loops intelligently adjust charging current.

IP5389 has a built-in 14bit ADC to accurately measure battery voltage and current. IP5389 has a built-in power calculation method that can accurately obtain battery power information. The battery power curve can be customized to accurately display battery power.

IP5389 supports 4 LED power display, supports 88, 188 and other digital tube power display; supports lighting function; supports buttons.

IP5389 integrates USB C Power Delivery PD2.0/PD3.0/PPS protocol, integrated physical layer protocol (PHY), and hardware bidirectional mark codec (BMC) module.

Supports PD2.0/PD3.0 bidirectional input/output protocol and PPS output protocol. Maximum support for 100W power output, input supports 5V, 9V, 12V, 15V, 20V voltage ranges, output supports 5V, 9V, 12V, 15V, 20V voltage range output broadcast capability 5V/3A, 9V/3A, 12V/3A, 15V/3A, 20V/3A, PPS 3.3~21V/3A.
