原先使用的是BQ27441-G1A,电池不变的情况能否直接用BQ27441-G1B?如果能替换,需要修改哪些地方?
Johnsin Tao:
Hi注意两种芯片使用的情况不同的:The bq27441-G1A should be used if the cathode is a traditional LiCoO2 chemistry and/or the battery data sheet recommends a maximum charging voltage of 4.2 V. The bq27441- G1B should be selected if the cathode is a lithium-manganese type and/or the maximum recommended charging voltage is 4.3 V or 4.35 V.

是的,但是由于客户购买的时候弄混了,产品已经加工好,想看看能不能使用?
