BQ24725A: SBS 1.1 Compliant Alternative?

Part Number: BQ24725A
Other Parts Discussed in Thread: BQ25710, BQ24780S

Hello!

Customer is looking for SBS 1.1 compliant battery charger. As I've browsed through our products and by googling, it seems that only gauges are. Can you please help confirm if this is really the case -- if there is indeed no SBS compliant battery charger?

Thank you and happy holidays!

  • Hey Elisha,

    We do have charger's that compatible with our SBS gauging products. The SBS capable gauges typically have a broadcast mode where they will communicate with our SMBus controllers such as the BQ24725A, BQ24780S, and BQ25710. These devices will all have the same register addresses for Charging Voltage and Charging Current which an SBS host or gauge can communicate to. 

    Section 5.2 and 5.3 of the Smart Battery Specification define these two register addresses as 0x14 and 0x15.

    Regards,

    Joel H
