BD64950EFJ-E2

Overview

The BD64950EFJ-E2 is a DC brush motor driver IC from ROHM Semiconductor, designed for single-channel H-bridge applications. It supports a supply voltage range of 8 V to 40 V and delivers a continuous output current of 3.5 A with a peak capacity of 6 A. The device operates within a temperature range of -25°C to +85°C and features a low operating supply current of 2.4 mA. Packaged in an 8-pin HTSOP-J format with exposed pad, it integrates current limit protection and direct PWM control capabilities.

Feature Summary

• Integrates a built-in single H-bridge circuit specifically configured for DC brush motor drive applications.
• Supports low power consumption through direct PWM control or PWM constant current control modes.
• Includes built-in protection circuits to enhance system reliability and safeguard against operational faults.

Applications

• DC brush motor control in home appliances
• Motion control systems requiring single-channel drive
• Industrial automation equipment with moderate current demands

Procurement Notes

Verify the specific suffix E2 to ensure compatibility with required packaging and RoHS compliance standards. Confirm that the application environment remains within the specified -25°C to +85°C operating temperature range. Ensure the load voltage does not exceed the 40 V withstand rating. Check that the continuous current requirement stays below 3.5 A to prevent thermal overload. Validate that the HTSOP-J8 package footprint matches the PCB design constraints.

Selection Notes

Select this component when a single H-bridge driver is sufficient for the target motor. Consider the 3.5 A continuous current limit as the primary constraint for motor sizing. Evaluate the need for PWM constant current control if precise torque regulation is required. Assess the thermal performance requirements given the exposed pad package type. Compare against alternative drivers if higher phase currents or multiple motor channels are necessary.
