This document describes the technical details of the H-bridge drivers BD6220, BD6221, BD6222, BD6225, BD6226, BD6227 for brush motor applications. These full bridge drivers can operate at a wide range of power supply voltages (from 3V to 36V), supporting output currents of up to 2A. MOS transistors in the output stage allow for PWM signal control, while the integrated VREF voltage control function of previous models offers direct replacement of deprecated motor driver ICs. These highly efficient H-bridge driver ICs facilitate low-power consumption design.
This technical note provides an overview of ROHM's BD6220‑BD6227 series H‑bridge driver ICs for brush‑motor applications. It lists key features such as selectable channel configurations, low standby current, and built‑in protection circuits.
The document includes absolute maximum ratings, operating conditions, detailed electrical characteristics, pin‑out tables for each package type, and packaging/tape‑and‑reel information. It is intended as a reference for designers integrating these drivers into audio‑visual, automotive, and other electronic equipment.

The drivers operate from 6 V to 15 V under normal conditions, with an absolute maximum rating of 18 V.
Each device provides four protection circuits: over‑current protection (OCP), over‑voltage protection (OVP), thermal shutdown (TSD), and under‑voltage lock‑out (UVLO).
The standby current is specified as up to 10 pA.
The drivers accept PWM control signals from 20 kHz up to 100 kHz.
