Part Number: BQ25720 Other Parts Discussed in Thread: BQ25731 您好,请问采用PD3.0的Type-c适配器协议充电,需要在充电管理芯片前端加一个type-c取电芯片吗,我看到参考手册里直接把Type-c适配器接到芯片上,没有接cc1和cc2引脚,那这个是怎么取电压的呢?
您好,请参考下面的schematic checklist 确认电路和layout 0552.BQ2570X_BQ2571X_BQ2572X_BQ2573X_SchematicChecklist.pdf For layout guidance, please see the following FAQ. https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/1032723/faq…
您好,请参考下面内容
when VBUS exceeds VVBUS_UVLOZ or VBAT exceeds VVBAT_UVLOZ. 5 ms after either VBUS or VBAT becomes valid, the charger resets all the registers to the default state. Another 5 ms later, the user registers become accessible to the host.
