BD6231F-E2

Overview

The BD6231F-E2 is a single-channel H-bridge motor driver IC from Rohm Semiconductor, designed for DC brush motors. It operates with a supply voltage range of 6V to 32V and delivers a continuous output current of 1.0A per channel. The device features an on-resistance of 1.5 ohms and utilizes power MOSFET technology. It supports interface control via ON/OFF signals and includes integrated control and power stages. The component is housed in an 8-SOP package with dimensions of 5mm x 4.4mm x 1.5mm. It functions within a junction temperature range of -40°C to +150°C.

Feature Summary

• Integrated full H-bridge driver combining control logic and power MOSFET stages for DC brush motor applications
• Supports reversible operation through simple ON/OFF interface control signals
• Designed for high thermal performance with a wide operating junction temperature range up to 150°C

Applications

• Media players requiring compact motor drive solutions
• Small DC brush motor control systems
• Automotive interior mechanisms such as seat adjusters or window lifts

Procurement Notes

Verify the specific suffix E2 against the manufacturer's latest datasheet to confirm RoHS compliance and lead-free status. Ensure the SOP-8 package variant matches your PCB footprint requirements. Confirm that the 1.0A current rating aligns with your motor's operational load under expected thermal conditions. Check for any updated flammability or whisker information documents prior to final design approval.

Selection Notes

Select this component when a single-channel H-bridge solution is required for low-power DC brush motors. It is suitable for designs needing a compact 8-pin surface mount package. Consider the 1.5 ohm on-resistance for efficiency calculations at 1.0A loads. Verify that the 6V to 32V supply range matches your system's power architecture. This part integrates both logic and power stages, reducing external component count compared to discrete solutions.

Part Context

The BD6231F-E2 belongs to Rohm's series of DC brush motor drivers rated for up to 36V maximum voltage. It is part of the BD6231 family, which focuses on integrated H-bridge solutions. The E2 suffix typically denotes environmental compliance variations within the product line. These drivers are engineered for reliability in consumer electronics and automotive interior applications where space and cost efficiency are critical.

Replacement Considerations

Check the BD6231F-BZE2 as a potential alternative if different packaging or environmental certifications are required. Verify pin compatibility and electrical specifications before substitution. Consult the manufacturer's cross-reference guide for exact functional equivalents.
