Getting Started

To evaluate this IC, designers should refer to the BQ24013EVM evaluation module to test charging profiles and thermal performance. Ensure the ISET resistor is sized correctly to program the desired constant-current limit up to 1A. Layout priority should be given to the thermal pad of the 10-VSON package to manage heat dissipation during high-current charging.
