BQ25172: find a NiMH battery management IC

Hi Henry

The BQ25172 would not be a good fit for 9V and 1.5A charge current. 

Would a switching converter be an option?

Do you require a standalone unit or have an MCU that manage the battery charger?

Hi Sir,

Would a switching converter be an option? => Please advise it.

Do you require a standalone unit or have an MCU that manage the battery charger? => Need a standalone unit, we aim to find a solution that replaces the LTC4011, and meets the customer's design requirements.

Hi Henry

We have switching chargers that can be adapted to change NiMH but require external MCU to configure and manage the device.  See BQ24105 application note, here.

How many cells are used in your application?

Hi Sir,

How many cells are used in your application? => Two cells in a series.

May I know if the application note supports the top-off charge function?

Hi Henry 

Checking on this.
