Operating from a 4V to 17V input, it supports programmable charge currents up to 4.5A with high switching frequency (1.5MHz) for small external components. The dynamic power-path management feature independently powers the system from the input while charging the battery, ensuring system stability even when the battery is deeply discharged. Battery supplement mode automatically draws from the battery when the input cannot supply enough current. USB OTG boost mode allows the battery to power external USB devices. Comprehensive safety features include input overvoltage, battery overvoltage, charge overcurrent, thermal regulation, and short-circuit protection.","working_principle":"The BQ24133RGYR operates as a synchronous buck battery charger with power path management. Key subsystems include: (1) Synchronous Buck Converter - a current-mode PWM buck converter steps down the input voltage to charge the battery at up to 4.5A with 1.5MHz switching; (2) Power Path Management - the input powers the system load first, with remaining current going to charge the battery; this ensures system operation even with a dead battery; (3) Charge Controller - a state machine manages pre-charge, constant-current, constant-voltage, and termination phases; (4) Supplement Mode - when system load exceeds input capability, the battery supplements the system through an internal path; (5) OTG Boost - in OTG mode, the converter operates in reverse as a boost converter, generating 5V on the input from the battery; (6) Safety - multiple comparators and timers monitor for fault conditions.","pin_description":"
