Notice! ! ! The battery terminal current is relatively large during high-power input and output, so pay attention to battery selection (LG M50T 21700 is recommended)

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.

The BM3451 series is a professional 3/4/5-cell rechargeable battery protection chip with high integration characteristics. It is suitable for power tools, electric bicycles, and UPS backup power supplies.

BM3451 realizes battery overcharge, over-discharge, discharge over-current, short circuit, charging over-current, temperature protection and other protection functions by detecting the voltage, charge and discharge current, and ambient temperature of each battery, and adjusts overcharge, over-discharge, and temperature protection through external capacitors. Over-discharge and over-current protection delay.

BM3451 provides a battery capacity balancing function to eliminate the capacity differences of each battery in the battery pack and extend the life of the battery pack. BM3451 can realize cascading of multiple chips to protect battery packs of 6 or more cells.

PCB size is 70*33mm, and there is currently no casing (preparing to use 3D printing to make the casing, modeling in progress)

The word "neng" is dusty, it's not a process problem

For TYPE-A interface protocol testing, the VOOC DASH protocol is supported, but the low-voltage and high-current protocol USB meter cannot test it. The QC protocol supports QC3.0 and supports up to 12V output. The USB meter can’t detect it either, but it can be detected by using it.

TYPE-C interface protocol test, supports maximum PD 20V 5A 100W output, PPS supports 3.3-21V 3A output

In the charging test, since the test battery pack uses 4 series of 1 parallel 2500mAh power 18650 batteries, the maximum input is only 85W. At this time, the battery terminal current is 5A, and 2C is basically the limit of this battery.

The 100W input and output test, VOOC DASH protocol test, and shell 3D file may be updated in the future. Gu...
