BD67891MUV-E2

Overview

The BD67891MUV-E2 is a three-phase brushless DC motor pre-driver manufactured by ROHM Semiconductor. It operates within a supply voltage range of 2.3 V to 5.5 V and supports load voltages from 20 V to 40 V. The device provides five outputs with an output current capability of 50 mA and a typical operating supply current of 65 µA. It features a maximum power dissipation of 880 mW and functions across a temperature range of -25°C to +85°C. The component is housed in a 32-pin VQFN surface-mount package.

Feature Summary

Directly drives external P-channel and N-channel FETs for motor control
Built-in logic input pull-down resistors ensure stable signal states
Supports multiphase BLDC motor applications with half-bridge configuration

Applications

Brushless DC motor control systems
Fan motor drivers
Optical disk drive (ODD) mechanisms

Procurement Notes

Verify the specific suffix E2 against the manufacturer's datasheet to confirm compliance with RoHS directives and lead-free manufacturing standards. Confirm that the VQFN-32 package dimensions match your PCB footprint requirements. Ensure the input voltage does not exceed the 5.5 V maximum rating during operation.

Selection Notes

Select this component when a low-power pre-driver for three-phase BLDC motors is required. It is suitable for designs needing direct FET gate driving without integrated high-side or low-side power stages. Consider the 65 µA quiescent current for battery-operated applications where standby power consumption is critical.

Part Context

This part belongs to ROHM's PMIC Motor Driver Multiphase Brushless DC category. It serves as a pre-driver stage, distinct from integrated power drivers, requiring external MOSFETs for high-current switching. The VQFN-32 package allows for compact surface-mount integration in space-constrained electronic devices.

Replacement Considerations

BD67891MUV is listed as an alias for this part number. Verify pinout compatibility if substituting with other ROHM three-phase pre-drivers such as the BD67871MWV-Z series, noting differences in PWM control modes and package types.
