你好,有几个问题
BQ24610電路设定如下
- The battery pack is 2-Cell.
- ISET1 is set at 1.5A
- ISET2 is set at 0.2A
- ACSET is set at 1.7A
- Rsr = 0.01Ohm
- TCC pin is connected to 0.1uF
- VFB pin is set at 2V when the battery is fully charged at 8.4V
- TS pin is valid and (the resistors are set at the correct value)
- CE pin is pulled to VREF
- All other components followe the reference design/schematic
1. Pin VTTC接了一个0.1uF电容到GND,
a. 当没有接电池时,该pin电压为1.25V。
b. 当接了电池时,该pin会随着电池电压变化,大约落在1.10V~1.00V之间,这样正常吗?
2. 当电池电压为6.8V~7V左右时,插上适配器,充电行为正常,约莫三个多小时后,电池电压升至7.88V~8V时,充电无故停止,是甚么原因呢?
3.接续2,重新拔插适配器,充电电流仍为1.5A,但约莫20~30分钟之后又会自动停止充电,是甚么原因呢?
Thanks
插上适配器
