BQ76952: TS1 Configuration

Dylan You

Part Number: BQ76952

Dear Teams,

My customer is using BQ76952. Could I ask following questions from you?

1. When we use TS1 to configure BQ76952's internal NTC temperature calculation mode, will there any requirements on NTC's B value because I have not found it in the datasheet and TRM?

Thanks!

Hi Dylan,

There is a tool in the BQ76952 product folder to calculate the coefficients for a specific thermistor. Here is the link: https://www.ti.com/tool/BQ769X2-THERMISTOR_COEFF_CALCULATOR

Have they tried using this tool already? Can you let me know which NTC they are using? If they have trouble with this, you can send me the R/T table for the thermistor and I can help calculate the coefficients.

Best regards,

Matt
