BQ40Z50 使用难度高,是否TI有使用流程教程?

Other Parts Discussed in Thread: BQ40Z50, BQ40Z60

BQ40Z50 有近十来个英文文档,大量的寄存器和系统工作原理描述。为了实现四串两并锂电池的管理,耗费大量精力。是否有使用流程描述文档,哪些寄存器是要配置的,哪些是不用的。如何通过SMBus来配置,感觉文档庞大,不够详细。

  • 文档的很多内容是有重叠的。

    bq40z50 Data Memory Programming for Mass Production

  • 您好,

    請問有bq40z50 data programming的資料可以提供嗎?類似附件20zxx系列,目前在TI網站上只找到calibration的資料。因為我司是做電池保護板的設備,客戶端需要將bq40z50 data programming & calibration的功能加到我司設備上。

    麻煩了,謝謝

  • Hi Michael,

    請問BQ40Z60要如何設定,EVM才會自動充放電?

    我現在只能透過EV2300手動開關FET使電池可以輸出至VSYS

    謝謝

  • 11.1.18 ManufacturerAccess() 0x0022 FET Control

    This command disables/enables control of the CHG, DSG, and PCHG FET by the firmware. The initial setting is loaded from MfgStatusInit[FET_EN]. If ManufacturingStatus[FET_EN] = 0, sending this command allows the FW to control the PCHG, CHG, and DSG FETs and the ManufacturingStatus[FET_EN] is set to 1 and vice versa. In UNSEALED mode, the ManufacturingStatus[FET_EN] status is copied to MfgStatusInit[FET_EN] on a reset. Hence, the device will remain on its latest FET control status prior to a reset.
