Product details

The 10 A max charge current places this part in the high-current synchronous buck class, not the linear charger tier. That means the external pass FETs, inductor, and input/output capacitors must be sized for the 10 A continuous path.

Fault protection set

On-die fault protection covers overcurrent, overvoltage, overtemperature, and short-circuit events. This reduces the need for external supervisory ICs or discrete comparators on the charge path. The overtemperature protection is particularly relevant for the 10 A charge current in confined enclosures — the IC self-limits before the inductor or FETs exceed their ratings.

Frequently asked questions

Is the BQ24617RGER compatible with 4-cell Li-Ion batteries?

Yes. The BQ24617RGER supports 1 to 5 cells, so a 4-cell Li-Ion pack (nominal 14.8 V, regulation at 2.1 V per cell = 8.4 V for 4 cells in 2-series? Wait — the battery pack voltage is 2.1 V, which is the per-cell regulation voltage. For a 4-cell series pack, the total regulation voltage is 4 × 2.1 V = 8.4 V. The IC handles 1 to 5 cells, so 4 cells is within range.

Does BQ24617RGER support USB input?

The input voltage supply maximum is 24 V, which covers standard USB PD voltages (5 V, 9 V, 15 V, 20 V). However, the IC does not include USB-specific handshaking (e.g., BC1.2 or PD negotiation); the input source must already provide the correct voltage within the 24 V max.

What battery chemistries does BQ24617RGER support?

It is designed for Lithium Ion and Lithium Polymer chemistries.
