It delivers a constant charge current up to 3A to a battery pack with a maximum voltage of 4.62V, making it suited for portable devices, power banks, and IoT endpoints that need a compact charging solution with host-controlled current programming. The I²C interface allows the system microcontroller to adjust the charge current in real time, which is useful for thermal management, input current limiting, or matching different cell capacities without a hardware resistor change.
3A charge current and thermal design
At 3A charge current, the 30-DSBGA package dissipates significant heat. The over-temperature protection provides a safety net if the thermal path is marginal.
Fault protection set reduces external BOM
Integrated over-current, over-temperature, and over-voltage protection means the BQ25600YFFT handles the safety monitoring internally. The 13.5V maximum supply voltage covers typical 5V USB input with margin for transients.
