BQ24190: Inquiry about alternative availability (BQ24297)

Part Number: BQ24190
Other Parts Discussed in Thread: BQ24297, BQ24195

Hi, Support Team

A customer is using the BQ24190. However, due to an issue on the current delivery date, we are reviewing a product that can be replaced immediately without changing the PCB.

In this regard, please confirm the following inquiries.

BQ24297 is a product different from BQ24190 only in pin 12.

The circuit diagram below is a circuit to which BQ24190 is applied.

1. When applying BQ24297, TS circuit is connected to pin 12 (shipping mode enable pin).

    Can it be applied?

2. Are the control registers of BQ24190 and BQ24297 the same?




  • MJ,

    1. No.

    2. The register functions are similar, but the register setting values could be different.

    Please note that BQ24190 is 17V, 4.5A charger while BQ24297 is 6.2V, 3A charger. BQ24195 is closer to BQ24190.
