The DPPM feature independently manages the power path between the input source, the system load, and the battery, ensuring that the system always receives power even when the battery is deeply depleted. When the input source current is limited (e.g., USB 500mA), the DPPM automatically reduces the charge current to maintain system power, and only charges the battery with the remaining available current. This prevents system brownouts during USB charging. The device supports dual input sources (USB and adapter) with input overvoltage protection at 6.4V. The charge current is programmable up to 1.5A via an external resistor, with USB-specific current limit settings of 100mA and 500mA. The default charge voltage is 4.2V with +\/-0.5% accuracy, and can be adjusted via an external resistor divider. Safety features include battery temperature monitoring through the TS pin with an NTC thermistor, charge safety timer, and thermal regulation that reduces charge current when the junction temperature exceeds 120C.","working_principle":"The BQ24075RGTR manages three power paths: input, system, and battery. (1) Power Path Management: The input power is first used to supply the system load (SYS pin). Any remaining current is directed to charge the battery (BAT pin). When the input current is insufficient to supply both the system and the charger, the DPPM circuit reduces the charge current to maintain the system voltage above the DPPM threshold (typically VBAT + 200mV). (2) Supplement Mode: If the system load exceeds the input current capability, the battery supplements the system through an internal FET, preventing system voltage drop. (3) Charging: The charger follows CC\/CV profiles: constant current (fast charge) at the programmed rate, then constant voltage at 4.2V with taper current termination. A preconditioning phase charges deeply depleted batteries at reduced current. (4) Input OVP: When the input voltage exceeds 6.4V, the input FET disconnects the source, protecting the system. (5) Thermal Regulation: If the junction temperature exceeds 120C, the charge current is reduced to limit power dissipation, preventing thermal shutdown while maintaining charging.","pin_description":"
