Datasheet DC Brush Motor Drivers (18V Max) BD622xxx Series General Description Key Specifications These H-bridge drivers are full bridge drivers for brush Supply Voltage Range: 18V(Max) motor applications. Each IC can operate at a power Maximum Output Current: 0.5A / 1.0A / 2.0A supply voltage range of 6V to 15V, with output currents of Output ON-Resistance: 1.5 / 1.5 / 1.0 up to 2A. MOS transistors in the output stage allow PWM PWM Input Frequency Range: 20kHz to 100kHz speed control. The integrated VREF voltage control Standby Current: 0A (Typ) function allows direct replacement of discontinued motor Operating Temperature Range: -40C to +85C driver ICs. These highly efficient H-bridge driver ICs facilitate low-power consumption design.
