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: 20kHz to 100kHz allow PWM speed control. The integrated VREF voltage Standby Current: 0A (Typ) control function allows direct replacement of discontinued Operating Temperature Range: -40C to +85C motor driver ICs. These highly efficient H-bridge driver ICs facilitate low-power consumption design.
