ROHM's Flexible Brushed DC Motor Driver ICs for a Wide Range of Applications
Executive Summary
- ROHM Semiconductor announced the mass‑production launch of two new brushed DC motor driver integrated circuits: BD60210FV (dual H‑bridge, 20 V) and BD64950EFJ (single H‑bridge, 40 V).
- Both devices feature ultra‑low standby current (typ. 0 µA, max 1 µA), high current capability, and versatile packaging aimed at reducing external component count in consumer and industrial applications.
- The ICs are now available for purchase through major online distributors (DigiKey, Mouser, Farnell) together with evaluation boards to accelerate design adoption.
Key Details
- BD60210FV – Dual‑channel H‑bridge motor driver:
- Input voltage range 8–18 V
- Continuous current 1 A/phase (peak 4 A/phase)
- Supports two DC brushed motors, bipolar stepper motors, or solenoid drivers
-
Eliminates need for boost circuitry, reducing board space and component count
-
BD64950EFJ – Single‑channel H‑bridge motor driver:
- Withstand voltage 40 V
- Continuous current 3.5 A (peak 6 A)
- Supports direct PWM and constant‑current PWM control
-
Low on‑resistance design minimizes heat generation
-
Power Efficiency – Ultra‑low standby current: typical 0.0 µA, maximum 1.0 µA, contributing to significant power savings in standby mode.
-
Production & Availability – Both ICs are now in mass production; online sales have commenced. Evaluation boards (BD60210FV‑EVK‑001 and BD64950EFJ‑EVK‑001) are available for design verification.
-
Target Applications –
- Consumer: refrigerators, air conditioners, printers, robotic vacuum cleaners, water heaters, rice cookers, humidifiers.
-
Industrial: automatic doors/shutters, small conveyors, power tools, other compact motor control systems.
-
Company Outlook – ROHM indicated it will continue expanding its motor‑driver portfolio to support energy‑efficient consumer and industrial equipment.
