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 goes up, I2R
losses go up as well)

| Hello, First thanks for your answers regarding H-Bridges and especially the LM18200. This H-Bridges would be used with 12V DC motors which can sink up to 12Amp each and I have plenty of room to put them. But there is still something that puzle me : (...)
