11 Function description

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. Figure 4 Boost efficiency curve 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.

V1.31 http://www.injoinic.com/ 8 / 13 Copyright © 2019, Injoinic Corp. Key / Lights / NTC 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, whi ch 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. 82K RNTC=100K B=3950 VL=1.32V/1.52V NTC COMP HT LT V=20uA*(R1//RNTC) VH=0.38V/0.56V key flashliggt KEY Figure 5 Schematic diagram of key, lights, NTC In the charging state: When NTC PIN detects a voltage of 1.32V, it means that the battery is 0 degrees , and stops charging the battery; When NTC PIN detects a voltage of 0.56V, it means that the battery is at 45 degrees, and stops charging the battery; In the discharge state:When NTC PIN detects a voltage of 1.52V, it means that the battery is -15 degrees low, and stops charging to discharge to the outside; When NTC PIN detects a voltage of 0.38V, it means that the battery is 60 degrees, and stops discharging to the outside; If the project does not require NTC, you need to connect the KEY pin to a 51K resistor to GND. Otherwise, it may cause abnormal charging and discharging. When the IP5 407 detects a key press, it will maintain the NTC detection result before the key is pressed, and the NTC detection returns to normal after the key is released.
