Product features:

Product module parameters:

Size: 65mm * 32.5mm ultra thin four corner hole with diameter of 3mm

Output interface: USB-A + USB-A + type-C supports fast charging output (see the specification for fast charging protocol)

Input interface: Micro + type-C supports fast charging input (see the specification for fast charging protocol)

Battery type: 3.7V battery (assembly or 18650 lithium battery) single section in parallel, unlimited capacity, the larger the capacity, the longer the charge and discharge time, for safety, please add a protection board for the battery, the main board has positive and negative poles, the battery can not be connected reversely, and the consequences of connecting reversely burning the main board are at your own risk!!!

Fast charging indicator: input / output high voltage fast charging indicator

Conversion efficiency: efficiency 95% (different voltage power efficiency varies) see the specification for details

Key press: if the key press lasts longer than 60 ms but less than 2 s, it is short press action. Short press will turn on the power indicator and boost output. If the key press is too long for 10 s, the whole system can be reset. If the key press is less than 30 ms, there will be no response.

Automatic detection function of mobile phone insertion:

Ip5328p automatically detects the insertion of the mobile phone, immediately wakes up from the standby mode, turns on the boost voltage of 5V to charge the mobile phone, saves the key operation, and supports the keyless scheme.

Function Description:

Low power locking 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 position of the power lamp will flash for 4 seconds

The first time to prompt; In the non charging state, if the battery voltage is too low to trigger low power shutdown, IP5328P will also enter the lock state.

In the locked state, in order to reduce the static power consumption, IP5328P does not have the function of mobile phone insertion detection, nor can it be activated by pressing the key. this

When the button action cannot activate the boost output, but the lowest 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 and constant voltage lithium battery charging management system supporting synchronous switch structure. It can automatically match different charging power

Pressure gauge.

When the battery voltage is less than 3V, 250mA trickle charging is adopted; When the battery voltage is greater than 3V, enter the input constant current charging, and the maximum charge of the battery terminal

0 a; When the battery voltage is close to the set battery voltage, enter the constant voltage charging; When the battery charging current is less than 300 Ma and the battery is charged

When the cell voltage is close to the constant voltage, stop charging. After charging, if the battery voltage is lower than 4.1V, restart the battery charging.

IP5328P adopts switch charging technology, and the switching frequency is 500KHz. The maximum input power is 10W when the common 5V input is charged; Fast charge input

When charging, the maximum input power is 18W. The maximum charging current of the battery can reach 5.0A, the charging efficiency can reach 94%, and the charging time can be shortened by 3 / 4.

IP5328P will automatically adjust the charging current to adapt to the adapter with different load capacity.

IP5328P does not support charging and discharging at the same time. In the charging state, the output discharge port will be closed to prevent the input high voltage from damaging the charged equipment.

boost

IP5328P integrates a synchronous switching converter system supporting high-voltage output, which supports 5V ~ 12V wide voltage range output and negative voltage

The load carrying capacity is 5V-3.1A, 7V-2.4A, 9V-2.0A and 12V-1.5A respectively. The switching frequency is 375 kHz. Built in soft start

Function, to prevent the fault caused by excessive impulse current during startup, integrated output over-current, short circuit, over-voltage, over temperature and other protection functions,

Ensure that the system works stably and reliably.

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.
