Module parameters:
Size: 65mm*32.5mm ultra-thin four-corner hole diameter 3mm
Output interface: USBA+USBA+TYPE-C supports fast charge output (see the specification for the fast charge protocol)
Input interface: MICRO + TYPE-C supports fast charging input (see the specification for the fast charging protocol)
Battery type: 3.7V battery (aggregate or 18650 lithium battery) in parallel with single cells, the capacity is not limited, the larger the capacity, the longer the charging and discharging time. For safety, please add a protective board to the battery. The main board has positive and negative poles, and the battery is not allowed. If you connect it backwards, you will burn the motherboard at your own risk! ! !
Fast charge indicator: input and output high voltage fast charge indicator
Conversion efficiency: 95% efficiency (different voltage and power efficiency vary) For details, please refer to the specification.
Press the key: The key duration is longer than 60ms but less than 2s, which is a short press action. A short press will turn on the battery indicator and boost output. A long press for 10s can reset the entire system. A key action of less than 30ms will not have any response.
Automatic detection of mobile phone insertion:
IP5328P automatically detects the phone is plugged in, immediately wakes up from standby mode, turns on the boost 5V to charge the phone, eliminating the need for key operations, and supports no key solutions.
Function description:
Low battery lock and activate
When the IP5328P is connected to the battery for the first time, no matter what the battery voltage is, the chip is in the locked state, and the lowest position of the battery 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, and it cannot be activated by pressing the button. this
When the button is pressed, the boost output cannot be activated, but the lowest position of the battery indicator will flash 4 times to indicate.
In the locked state, you must enter the charging state to activate the chip function.
Recharge
IP5328P has a constant current and 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, 250mA trickle charge is used; when the battery voltage is greater than 3V, it enters the input constant current charging, and the battery terminal is charged at the maximum
Electric current 5.0A; when the battery voltage is close to the set battery voltage, it enters 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 voltage, stop charging. After the charging is completed, if the battery voltage is lower than 4.1V, restart the battery charging.
IP5328P adopts switching charging technology with a switching frequency of 500kHz. When charging with ordinary 5V input, 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 can reach 94%, which can shorten the charging time by 3/4.
IP5328P will automatically adjust the charging current to adapt to adapters with different load capacities.
IP5328P does not support simultaneous charging and discharging, 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 5V~12V wide voltage range output, 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 malfunctions caused by excessive inrush current at startup, integrated output overcurrent, short circuit, overvoltage, overtemperature and other protection functions,
Ensure the 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 set temperature.
