« on: September 18, 2017, 04:08:27 AM »
Good day,all
Can I ask you some help? :)
I have made a toy car using LTC4054 ( LTC4054 Datasheet ) to charge 3.7V battery. When I debug it using phone,itís normal to charge.However, I donít know why now itís so hot when I charged it. Is the problem caused by battery?

Please help me!  It's urgent. Thank you in advance,
