DC Brush Motor Drivers (18V Max)

BD622xxx Series

General Description

These H-bridge drivers are full bridge drivers for brush motor applications. Each IC can operate at a power supply voltage range of 6V to 15V, with output currents of up to 2A. MOS transistors in the output stage allow PWM speed control. The integrated VREF voltage control function allows direct replacem ent of discontinued motor driver ICs. These highly efficient H-bridge driver ICs facilitate low-power consumption design.

Features

 Built-in Selectable One Channel or Two Channels

Configuration

 VREF Voltage Setting Pin Enables PWM Duty Control  Cross-Conduction Prevention Circuit  Four Protection Circuits Provided: OCP, OVP, TSD

and UVLO

Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over the absolute maximum ratings.
