We're using a BQ51013 to charge a lithium battery. At 500mA coming out of the BQ51, we measured the chip at over 140F. The BQ51 is on a small device and it's heat soaking everything, including the battery. This has been causing batteries to bulge.
Dropping the charge current down to 250mA reduces the BQ51013's temperature to 125F, but that's still too hot for the battery.
What can be done to reduce the BQ51013 temperature? It's heating up our entire device.
