This document introduces in detail the characteristics and features of BD6387EFV, BD6385EFV, BD6383EFV, BD6389FM 36V Hall driver. This series of products has low power consumption, high reliability and various protection functions. It adopts low ON resistance DMOS and high heat-radiation power package to reduce the heat generation of IC. As for its basic function, it is a low power consumption bipolar PWM constant current-drive driver with power supply's rated voltage of 36V and rated output current of 1.0A~2.2A.
This technical note describes the ROHM 36 V stepping‑motor driver series (BD6383EFV, BD6385EFV, BD6387EFV, BD6389FM). It outlines the driver’s high‑performance functions, protection circuits, and low‑ON‑resistance DMOS output, as well as the selectable excitation modes (full‑step, half‑step, quarter‑step, U‑step) and current‑decay settings.
The document provides absolute maximum ratings, electrical characteristics, pin‑out tables, block diagrams, usage notes, and ordering information. It also includes guidelines for thermal design, grounding, and handling of strong electromagnetic fields, aimed at designers integrating these drivers into printers, cameras, sewing machines, toys, robots and other equipment.
| Supply voltage (Voco) | 0 ~ 36 V |
|---|---|
| Rated output current | 1.0 A ~ 2.2 A |
| Operating temperature range | -25 °C ~ +475 °C |
| Maximum junction temperature (Tjmax) | 150 °C |
The driver operates from a single‑system supply of 0 ~ 36 V (rated 36 V).
The SELECT terminal chooses between CLK‑IN drive (logic low) and Parallel IN drive (logic high).
