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.
Functional Description:
● Low-Battery Lock and Activation
● When the IP5328P is first connected to a battery, regardless of the battery voltage, the chip is in a locked state, and the lowest battery indicator light will flash 4
● times as a prompt; when not charging, if the battery voltage is too low to trigger a low-battery shutdown, the IP5328P will also enter a 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 cannot be activated by a button.
● At this time the button action cannot activate the boost output, but the lowest battery indicator light will flash 4 times as a prompt.
● In the locked state, the chip function must be activated by entering the charging state.
Charging
● IP5328P has a constant current and constant voltage lithium battery charging management system that supports a synchronous switching structure. It can automatically match different charging
Voltage specifications.
● When the battery voltage is less than 3V, 250mA trickle charging is used. When the battery voltage is greater than 3V, constant current charging is initiated, with a maximum
● charge . When the battery voltage approaches the set battery voltage, constant voltage charging
● is initiated. Charging stops when the charge current is less than approximately 300mA and the battery voltage approaches the constant voltage. After charging is complete, if the battery voltage falls below 4.1V, charging is resumed.
● The IP5328P uses switching charging technology with a switching frequency of 500kHz. When charging with a standard 5V input, the maximum input power is 10W;
● when charging with a fast charging input, the maximum input power is 18W. The maximum charge current at the battery end can reach 5.0A, with charging efficiency reaching up to 94%, reducing charging time by three-quarters.
● The IP5328P automatically adjusts the charge current to accommodate adapters with different load capacities.
● The IP5328P does not support simultaneous charging and discharging. When charging, the output discharge port is disabled to prevent high voltage damage to the device being charged.
The boost
● IP5328P integrates a synchronous switching converter system that supports high-voltage outputs. It supports a wide 5V to 12V output voltage range, with
● load capacities of 3.1A for 5V, 2.4A for 7V, 2.0A for 9V, and 1.5A for 12V, respectively. It operates at a switching frequency of 375kHz. A built-in soft-start
● function prevents malfunctions caused by excessive inrush current during startup. Integrated protection features include output overcurrent, short-circuit, overvoltage, and overtemperature,
● ensuring stable and reliable system operation.
● The boost system's output current automatically adjusts with temperature to ensure the IC temperature remains below the set point.
