Motor Driver IC Blown up. Wish to know what went wrong Answered
I am using 11.1V 25C 3700mAh Lipo Battery for powering up Motor driver Card (Dual DC Motor Driver 20A) Motor driver Product Link: http://robokits.co.in/motor-drives/dual-dc-motor-driver-20a .
Basically, I tried connecting two motors instead of single Motor on each motor port on the driver. So in all 4 DC motors connected as the motors had no load. As per my calculations, all 4 DC motors together cannot draw more than 4 Amps of current. DC Motor Specifications 10 RPM High Torque Dc Motor.

During this check I noticed that one of the IC LR 7843 on the motor Driver Card got burnt, the moment I powered it up with LiPo Battery.
Really don't Know why this happened.... Can someone please help me....
