BD6211F-E2

Overview

The BD6211F-E2 is a half-bridge brushed DC motor driver manufactured by ROHM Semiconductor. It operates within a supply voltage range of 3 V to 5.5 V and supports a maximum output current of 1 A. The device features an internal on-resistance of 1.0 ohm and a power dissipation rating of 680 mW. It utilizes a PWM interface for control and is housed in an SOP-8 surface-mount package. The component functions reliably across an operating temperature range from -40 °C to +85 °C, with a typical quiescent supply current of 1.5 mA.

Feature Summary

• Integrates a half-bridge output stage designed for driving brushed DC motors
• Supports pulse-width modulation (PWM) signal input for speed and direction control
• Includes built-in thermal protection mechanisms to prevent damage during overload conditions

Applications

• Small appliance motor control systems
• Automotive interior accessory drives
• Industrial automation micro-motor actuators

Procurement Notes

Verify the specific suffix E2 against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Ensure the SOP-8 footprint matches the target PCB design. Confirm that the 3 V to 5.5 V supply range aligns with the system power architecture before finalizing procurement orders.

Selection Notes

Select this component when a single-channel half-bridge driver is required for low-voltage brushed DC motors. It is suitable for applications demanding a compact SOP-8 footprint and moderate current handling up to 1 A. Consider thermal management requirements given the 680 mW power dissipation limit in enclosed environments.

Part Context

This part belongs to the BD6211F series of motor drivers from ROHM Semiconductor. It is categorized under PMIC Motor Drivers, specifically for bipolar brushed DC applications. The series provides integrated solutions for motion control in consumer and industrial electronics requiring simple interface and reliable performance.

Replacement Considerations

Consult official substitution lists for direct equivalents. Verify electrical parameters such as supply voltage range, output current capacity, and package dimensions to ensure functional compatibility without redesigning the host circuit board.
