BQ41Z50: 无法开启Boardcast模式

Part Number: BQ41Z50
Other Parts Discussed in Thread: BQSTUDIO

您好，
我们在参考 SLUAAF8 设计基于 BQ41Z50 的无MCU自动充电电池包。但是无法根据 BQ41Z50 的 Technical Reference Manual 开启Boardcast 模式。

我们设置了 SBS Configuration [BCAST] = 1 和 Initial Battery Mode [ChgM] = 0 ，但重启（不仅Reset，也包括 shutdown 和断开电池连接等硬重启）依然无法得到 Battery Mode [ChgM] = 0，ChgM在BQStudio中永远是红色的。

现象与以下几个帖子一致：

• BQ41Z50: Confusion about the relationship between InitialBatteryMode and BatteryMode register, and ability to change BatteryMode on the fly
• BQ41Z50: Charge control SMBUS Broadcast without MCU
• BQ41Z50: Battery Mode [ChgM] and [AM] always set after power-up, even when Initial Battery Mode [ChgM] is unset - Power management forum - Power management - TI E2E support forums

请问截至2026-4，目前BQ41Z50的固件仍然是不支持Boardcast吗？还是说开启SMBUS Boardcast需要Initial Battery Mode 和 BCAST 之外的更多条件？

Best regards.
