Controlled via SMBus, it charges 2-4 series Li-Ion cells at up to 10 A with \u00b10.5% charge voltage accuracy and \u00b13% charge current accuracy. The 700 kHz switching frequency allows compact inductor selection, while Dynamic Power Management (DPM) and thermal regulation ensure safe operation across all conditions.","working_principle":"The BQ24765 operates as a synchronous buck converter with SMBus control: (1) Power Stage \u2014 two integrated NMOS FETs (30 m\u03a9 each) switch at 700 kHz to step down the adapter voltage to the battery charge voltage. Type III compensation supports ceramic output capacitors. Adaptive dead-time control achieves 99.5% effective duty cycle; (2) SMBus Control \u2014 the host programs ChargeVoltage() (1.024-19.2V), ChargeCurrent() (128 mA-8.064 A), and InputCurrent() (256 mA-11.008 A) DAC registers with high resolution; (3) Dynamic Power Management \u2014 DPM reduces charge current when total input current approaches the adapter limit, ensuring adapter is never overloaded; (4) Thermal Regulation \u2014 when junction temperature reaches 120\u00b0C, charge current is automatically reduced to maintain safe operating temperature.","pin_description":"
