Its a MOSFET based bridge, the Vgs potential needed to put the FETs into full enhancement mode is 11.2v or thereabouts. At lower voltages the FETs operate in their linear range (their Rds value goes up) and they dissipate much more heat. (As Rds (...) (27 years ago, 20-Mar-98, to lugnet.robotics.handyboard)
