BQ27Z558: Inquiry about 1S Battery Pack Gauge IC with Specific Features

Part Number: BQ27Z558
Other Parts Discussed in Thread: BQ27Z746

Tool/software:

Dear TI Support Team,

I am looking for a battery gauge IC for a 1S battery pack that meets the following customer requirements:

  1. Capacity Calculation: The gauge IC should provide accurate capacity calculation for the battery pack.
  2. Protection Features: The IC should include protection functions to ensure safe operation.
  3. UART (One-Wire) Communication: The IC should support UART (One-Wire) communication for external interfacing.

Could you kindly provide information on any available TI gauge ICs that meet these requirements? Any recommendations or suggestions would be greatly appreciated.

Thank you for your assistance.

  • Hello, 

    We do not have any gauges that support UART communication. We do however have gauges that support HDQ communication which is one-wire communication. The BQ27z746 is a 1s gauge that has accurate capacity calculation, has integrated high-side protections, and supports HDQ one-wire communication. 

    Regards, 

    Jonny.
