Datasheet DC Brush Motor Drivers (36V max.) BD623xxx Series General Description Key Specifications These H-bridge drivers are full bridge drivers for brush Supply Voltage Range: 36V(Max.) motor applications. Each IC can operate at a wide range Maximum Output Current: 0.5A / 1.0A / 2.0A of power supply voltages (from 6V to 32V), with output Output ON resistance: 1.5 / 1.5 / 1.0 currents of up to 2A. MOS transistors in the output stage PWM Input frequency range: 20 to 100kHz allow PWM speed control. The integrated VREF voltage Standby current: 0 A (Typ.) control function allows direct replacement of deprecated Operating temperature range: -40 to 85 motor driver ICs. These highly efficient H-bridge driver ICs facilitate low-power consumption design. Packages (Typ.) (Typ.) (Max.)
