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 motor is preferred due to their simplicity, reliability and low cost. H-bridge driver ICs control the motor's direction, speed, braking and idling.
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.
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.
The BD62x2FP series 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.
The devices are designed to withstand up to 4 kV ESD.
