BD6231 H-bridge drivers

For brush motors H-bridge drivers (36V max.) BD6230, BD6231, BD6232, BD6235, BD6236, BD6237  Overview These H-bridge drivers are full bridge drivers for brush motor applications. Each IC can operate at a wide range of power supply voltages (from 3V to 36V), supporting output currents of up to 2A. MOS transistors in the output stage allow for PWM signal control, while the integrated VREF voltage control function of previous models offers direct replacement of deprecated motor driver ICs. These .
