Product details

Multi-chemistry charger with I²C control — what it does

The BQ24721RHBT: It handles a maximum battery pack voltage of 19.2V and accepts a supply rail up to 24V, with overcurrent fault protection built in.

Obsolete — plan the BOM transition

The BQ24721RHBT carries an obsolete lifecycle status — TI no longer manufactures this part in production volumes. For new designs or long-run production, evaluate a current-generation SMBus/I²C charger from the BQ247xx family with a similar cell-count and voltage rating.

Frequently asked questions

What is BQ24721RHBT's listed interface?

The BQ24721RHBT uses an I²C interface for communication with the host controller, allowing programmable charge current and voltage settings.
