BD6964F-E2

Overview

The BD6964F-E2 is a single-phase brushless DC motor controller and driver manufactured by ROHM Semiconductor. It features a half-bridge output configuration with two outputs, supporting a supply voltage range of 3.3 V to 15 V and load voltages from 3.3 V to 14 V. The device delivers an output current of 1 A and operates within a temperature range of -40°C to +105°C. It utilizes a PWM interface for control and consumes a working supply current of 3 mA. Packaged in an SOP-8 surface-mount format, it dissipates up to 780 mW.

Feature Summary

• Integrates quick start function, lock protection, and auto restart capabilities without requiring external capacitors.
• Provides lock alarm signal (AL) output for fault detection.
• Supports PWM speed controllable signals for precise motor management.

Applications

• Single-phase fan motor control
• Brushless DC motor applications
• Small appliance motion control

Procurement Notes

Verify the specific suffix E2 against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Ensure the SOP-8 package dimensions match the PCB footprint requirements. Confirm that the operating temperature range of -40°C to +105°C aligns with the target application environment. Cross-reference the 1 A output current rating with the thermal dissipation limits of the system design.

Selection Notes

Select this component when a fully integrated single-phase BLDC driver with low quiescent current is required. The SOP-8 package suits space-constrained surface-mount designs. Consider the 3.3 V to 15 V supply range for compatibility with various logic levels. The built-in lock protection and alarm output simplify system reliability monitoring compared to discrete solutions.
