Evaluation Board:

H-Bridge Motor Drivers

For DC Brush Motors

BD6212FP, BD6222FP, BD6232FP (2A / 5.5V, 15V, 32V)

●Introduction

No.0000000012

This application note will provide the steps necessary to operate and evaluate ROHM’s H-Bridge motor drivers using the BD62x2 evaluation

board. DC brush motors are increasingly required for a broad range of applications. DC brush motor is preferred due to their simplicity,

reliability and low cost. H-bridge driver ICs control the motor’s direction, speed, braking and idling.

●Description

This evaluation board has been developed for ROHM’s H-Bridge driver customers evaluating the BD62x2FP series. The BD62x2FP series

can operate across a wide range of power supply voltages (from 3V to 32V max), supporting output currents of up to 2A. PWM signal

control (20 kHz-100 kHz) or VREF control modes are used to vary motor rotation speeds. ROHM’s ICs are complete with over current

protection (OCP), over voltage protection (OVP), thermal shutdown (TSD) and under voltage lock out (UVLO) protection circuits while also

facilitating a low-power consumption design (10µA max). Overlap (shoot-through) protection to prevent high currents during motor reversal

or breaking is also built in. In addition, the devices are designed to withstand up to 4 kV ESD.

●H-Bridge Motor Driver Operation Modes

a) Stand-by mode

b) Forward mode

c) Reverse mode

d) Brake mode

e) Forward PWM control mode

f) Reverse PWM control mode

g) Forward VREF control mode

h) Reverse VREF control mode

●Applications

VCR; CD/DVD players; A/V equipment; optical disc drives; PC peripherals; car audio; car navigation systems; office automation equipment
