Datasheet DC Brush Motor Drivers (7V Max) BD621xxx Series General Description Key Specifications These H-bridge drivers are full bridge drivers for brush Operating Supply Voltage: 7V(Max) motor applications. Each IC can operate at a power Maximum Output Current: 0.5A / 1.0A / 2.0A supply voltage range of 3.0V to 5.5V, with output currents Output ON-Resistance: 1.0 / 1.0 / 0.5 of up to 2A. MOS transistors in the output stage allow PWM Input Frequency Range: 20kHz to 100kHz PWM 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.
