bq25504需要给超级电容设置过放保护电路吗?Battery Undervoltage Protection中提到
To prevent rechargeable batteries from being deeply discharged and damaged, and to prevent completely
depleting charge from a capacitive storage element, the undervoltage (VBAT_UV) threshold must be set using
external resistors.
是不是芯片内部有电池过放保护电路?
Jacky Wang(QD):
不需要的,内部有电池欠压保护。另外跟电池相比,超级电容的过充、过放都不会对其寿命产生负面影响,所以不需要单独保护电路。
