Other Parts Discussed in Thread: BQ40Z50-R1,
HI 您好
關於在78Z100 參數文件中 未看到BCAST 說明
這個應用是什
但在BQ40Z50-R1 有說明
If the [HPE] bit is enabled, MASTER mode broadcasts to the host address are PEC enabled. If the [CPE]
bit is enabled, MASTER mode broadcasts to the smart-charger address are PEC enabled. The [BCAST]
bit enables all broadcasts to a host or a smart charger. When the [BCAST] bit is enabled, the following
broadcasts are sent:
• Charging Voltage() and Charging Current() broadcasts are sent to the smart-charger device address
(0x12) every 10 to 60 s.
• If any of the [OCA], [TCA], [OTA], [TDA], [RCA], [RTA] flags are set, the AlarmWarning() broadcast is
sent to the host device address (0x14) every 10 s. Broadcasts stop when all flags above have been
cleared.
• If any of the [OCA], [TCA], [OTA], [TDA] flags are set, the AlarmWarning() broadcast is sent to a smartcharger
device address every 10 s. Broadcasts stop when all flags above have been cleared.
在默認使用上我是關閉的
1.BQ78Z100 在I2C 默認下是開啟的
功能是否跟BQ40Z50-R1 一樣 (因為是SMBS 才默認關閉) 但BQ78Z100 是沒有 [HPE] [CPE] 這旗標設置
2. BQ78Z100 若選擇關閉 BCAST 會不會影響 I2C 通訊
3. Q78Z100 BCAST 本身是虛設的?
