BM64300MUV-E2

Overview

The BM64300MUV-E2 is a three-phase brushless DC motor pre-driver IC designed for sine wave drive applications using external Nch+Nch FETs. It operates on a power supply voltage range of 28 V to 63 V, with a maximum Vcc of 100 V. The device detects rotor position via three Hall sensors and supports a PWM operating frequency of 40 kHz. It functions within an ambient temperature range of -40 °C to +105 °C and is housed in a VQFN-40 package measuring 6.0x6.0 mm.

Feature Summary

• Supports sine wave drive through automatic lead angle control and three-Hall sensor detection for quiet, low-vibration operation.
• Integrates built-in boost voltage circuitry and comprehensive protection features including over-current, thermal shutdown, and lock protection.
• Enables speed control via PWM duty input with configurable dead time, soft start, and power save functions.

Applications

• Fan motors
• Paper feeding devices
• Multi-prism equipment
• Optical disk drives

Procurement Notes

Verify the specific suffix E2 against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Confirm that the application does not require automotive-grade certification, as this standard-grade component is explicitly excluded from vehicle use. Ensure the design accommodates the required external Nch+Nch FETs and three Hall sensors for proper functionality.

Selection Notes

Select this component for general-purpose three-phase brushless motor control requiring sine wave drive characteristics. It is suitable for systems operating between 28 V and 63 V where external power transistors are preferred for higher current handling. Choose this part when integrated Hall sensor signal processing and automatic lead angle adjustment are required to minimize acoustic noise and vibration.

Part Context

This pre-driver belongs to ROHM's series of brushless motor controllers designed for general consumer electronics. It complements sensorless variants like the BM64070MUV by offering dedicated support for three-Hall sensor configurations. The family targets applications demanding high reliability and smooth torque performance without the complexity of full integration.
