Abstract:
The present invention is targeted at suppressing ringing and overvoltage.
A driver circuit (200) drives a plurality of loads (Z1 to ZN). A plurality of output terminals (Po1 to PoN) are connected to the plurality of loads (Z1 to ZN). A plurality of drivers (Dr1 to DrN) correspond to the plurality output terminals (Po1 to PON), and generate driving signals (Vo#) applied to the respectively corresponding load (Z#). A plurality of clamp circuits (260_1 to 260_N) correspond to the plurality of drivers (Dr1 to DrN), and include Schottky diodes (SD) connected to input nodes or output nodes of the respectively corresponding drivers (Dr).
