Frequently Asked Questions

How many Li-Ion cells can BQ24703PWRG4 charge simultaneously and at what charge voltage?

BQ24703PWRG4 controls 3 channels and supports adjustable charge voltage thresholds selectable via external resistors, making it suitable for 1S, 2S, and 3S Li-Ion cell stacks. Typical full-charge voltages are set to 4.2 V per cell, so a 2S pack would be regulated to approximately 8.4 V with tight accuracy.

What external MOSFET gate drive capability does BQ24703PWRG4 provide for high-current charger designs?

BQ24703PWRG4 sources up to 7.1 mA of gate drive current to control external N-channel or P-channel MOSFETs in the charge path. This gate drive strength is sufficient to switch typical 30 V to 60 V MOSFETs with gate charge up to 30 nC at frequencies compatible with synchronous buck charge topologies used in notebook adapters.

When should a designer choose BQ24703PWRG4 over a fully integrated charger IC for a 3S laptop battery design?

BQ24703PWRG4 suits designs requiring an external MOSFET to handle charge currents above 3 A, since the external switch can be sized for the thermal and current requirements independently. A 3S notebook battery running at 4 A charge current generates significant heat; placing the power dissipation in a discrete MOSFET rather than inside the IC keeps the 24-pin TSSOP package within its junction temperature limit while maintaining 8.4 V charge precision.
