L6206 PARALLELED OPERATION The outputs of the L6206 can be paralleled to increase the output current capability or reduce the power dissi- pation in the device at a given current level. It must be noted, however, that the internal wire ...
Page 15
To operate the device in parallel and maintain a lower over current threshold, Half Bridge 1 and the Half Bridge 2 of the Bridge A can be connected in parallel and the same done for the Bridge B as shown ...
