IP5328P Dual USB 18650Battery Charger treasure Tpye-c 3.7V to 5V 9V 12V Step up Fast Quick Charger Circuit Board QC2.0 QC3.0 Description Adopt Infinix IP5328P mobile power solution, four layers of gold plate, optimized layout and wiring, support multiple fast charging protocols, bidirectional 18W fast charging, a total of 4 charging interfaces can be supported: 2 USB-A output interfaces, 1 USB-C interface, 1 Micro USB interface, 4 interfaces all support fast charge, 2 USB-A ports support QC3.0, FCP, AFC, MTK, SFCP fast charge output, power up to 18W; support Apple, Samsung, BC1.2 agreement. The USB-C port supports USB PD bidirectional fast charge, and is compatible with FCP, AFC, SFCP fast charge input and QC3.0, FCP, AFC, MTK, SFCP fast charge output. MicroUSB supports FCP, AFC, SFCP fast charge input. Product module parameters:Size: 65mm*32.5mm ultra-thin corner hole diameter 3mm Output interface: USBA+USBA+TYPE-C supports fast charge output (see specification for details of fast charge protocol) Input interface: MICRO + TYPE-C supports fast charging input (see specification for details of fast charging protocol) Battery type: 3.7V battery (collection or 18650 lithium battery) connected in parallel in a single cell, the capacity is not limited, the larger the capacity, the longer the charge and discharge time, please add a protection board for safety, the motherboard has positive and negative points, the battery is not allowed If the connection is reversed, the motherboard will be burned at your own risk! ! ! Quick charge indication: input and output high voltage fast charge indicator Conversion efficiency: 95% efficiency (varies in power efficiency at different voltages) See the specifications for details Press the key: The duration of the key is longer than 60ms, but less than 2s, which is a short press action. Short press will turn on the power indicator and boost output. Pressing for longer than 10s will reset the entire system. There will be no response to key presses less than 30ms. Mobile phone insertion automatic detection function: IP5328P automatically detects the phone plug-in, immediately wakes up from standby, turns on the boost 5V to charge the phone, saves the key operation, and supports the keyless solution. Function description:Low battery lockout and activation When the IP5328P is connected to the battery for the first time, no matter what the battery voltage is, the chip is locked, and the lowest bit of the power light will flash 4 Prompt again; in the non-charging state, if the battery voltage is too low to trigger a low power shutdown, the IP5328P will also enter the locked state. In the locked state, in order to reduce static power consumption, the IP5328P does not have a mobile phone insertion detection function, nor can it be activated by pressing a button. this When the key is pressed, the boost output cannot be activated, but the lowest position of the power light will flash 4 times to prompt. In the locked state, you must enter the charging state to activate the chip function. Charge IP5328P has a constant current, constant voltage lithium battery charging management system that supports a synchronous switch structure. Can automatically match different charging power Pressure specifications. When the battery voltage is less than 3V, use 250mA trickle charging; when the battery voltage is greater than 3V, enter the input constant current charging, the battery terminal maximum charging Electric current 5.0A; when the battery voltage is close to the set battery voltage, enter the constant voltage charging; when the battery terminal charging current is less than about 300mA and the battery When the cell voltage is close to the constant voltage, stop charging. After charging, if the battery voltage is lower than 4.1V, recharge the battery. IP5328P adopts switch charging technology with a switching frequency of 500kHz. Normal 5V input charging, the maximum input power is 10W; fast charging input When charging, the maximum input power is 18W. The maximum charging current of the battery can reach 5.0A, and the charging efficiency is up to 94%, which can shorten the charging time by 3/4. IP5328P will automatically adjust the charging current to adapt to different load capacity adapters. IP5328P does not support the same charge and discharge, and the output discharge port will be closed in the charging state to prevent the input high voltage from damaging the charged device. Boost IP5328P integrates a synchronous switching converter system that supports high voltage output, supports a wide voltage range output of 5V~12V, negative The load capacity is 5V-3.1A, 7V-2.4A, 9V-2.0A, 12V-1.5A. The switching frequency is 375KHz. Built-in soft start Function, to prevent failure caused by excessive inrush current at startup, integrated output over current, short circuit, over voltage, over temperature and other protection functions, Ensure stable and reliable operation of the system. The output current of the boost system can be automatically adjusted with the temperature to ensure that the IC temperature is below the settemperature.
