Control System.
Boost
      IP5407 integrates a Boost DCDC converter with an output of 5V and a load capacity of 2.1A. The switching
frequency is 950KHz, 3.8V input, and the efficiency is 92% at 5V / 2.1A. Built-in soft-start function to prevent
malfunction caused by excessive inrush current during startup. Integrated output over-current, short-circuit,
over-voltage, over-temperature protection functions When an output overcurrent or short circuit is detected, the
output will be restarted every second to ensure that the system works stably and reliably. lP5407 will turn on the
5V boost output and power display after the BAT voltage is greater than 3.2V. When the output current is less
than 50mA and after 36s, the power display will be turned off and the output voltage will be fixed at 5V to enter
the low power consumption mode. When the IP5407 detects that the BAT voltage is lower than 3.0V, it will turn
off the output. After the BAT voltage rises, it needs to be charged and activated to output normally.
Charge
      IP5407 has a constant current, constant voltage lithium battery charger with a synchronous switch structure.
When the battery voltage is less than 3v, 100mA slip current charging is used; when the battery voltage is greater
than 3V, it enters constant current charging, and the VIN input current limiting loop works; when the battery
voltage is greater than 4.2V, it enters constant voltage charging.After the charging is completed, if the battery
voltage is lower than 4.1V, restart the battery charging
      P5407 adopts switch charging technology, with a switching frequency of 500KHz and a charging current of
2.0A at the VIN input terminal. The charging efficiency is up to 91%.
     Adaptive power path management, support charge and discharge simultaneously.
     IP5407 charging will automatically adjust the charging current to adapt to adapters with different load
capacities, without pulling the charger.
      IP5407's keys, lighting lamp drive, and NTC temperature detection are realized by time-multiplexing. Refer
to the schematic diagram in Figure 5
     IP5407 can recognize long and short button operation
        The key duration is longer than 50ms, but less than 2s, which is a short press action. A short press will
           turn on the power indicator and boost output.
        If the key is pressed for longer than 2s, it is a long-press action. A long-press will turn the lighting LED
           on or off.
        There will be no response when the key action is less than 50ms.
     IP5407 integrates NTC function to detect battery temperature. When IP5407 is working, NTC
PIN outputs a current of 20uA. At the same time, it detects the voltage of the NTC PIN to
determine the current battery temperature.
