BD7966EKV

Power Management - Specialized Overview

The BD7966EKV is a silicon monolithic integrated circuit designed as a power driver for automotive CD and DVD mechanisms. Manufactured by ROHM Semiconductor, this component supports BLDC motor control with a maximum IGBT collector current of 500mA. It utilizes an HTQFP-64V surface-mount package configuration. The device features a 7-channel BTL output structure, enabling efficient drive capabilities for multi-motor applications within optical disc drives.

Power Management - Specialized Feature Summary

• Integrated power driver architecture optimized for automotive audio/video mechanism control
• Supports Brushless DC (BLDC) motor operation with dedicated channel outputs
• Utilizes 7-channel Bridge-Tied Load (BTL) configuration for enhanced drive efficiency

Power Management - Specialized Applications

• Automotive CD player mechanism drive systems
• Automotive DVD player spindle and tray motor control
• Multi-motor actuation in car audio/video units

Power Management - Specialized Procurement Notes

Verify the exact suffix EKV against the manufacturer's official datasheet to confirm pinout and thermal specifications. Ensure the HTQFP-64V package compatibility matches your PCB footprint design. Cross-reference the 500mA current rating with your specific motor load requirements to prevent overcurrent conditions during procurement validation.

Power Management - Specialized Selection Notes

Select this component when designing automotive optical drive circuits requiring integrated BTL drivers for BLDC motors. The 64-pin HTQFP package suits space-constrained automotive modules. Consider the 500mA per-channel limit when sizing motor loads. This IC replaces older discrete driver solutions by integrating multiple channels into a single monolithic silicon device.

Power Management - Specialized Part Context

This part belongs to ROHM's family of power management and driver ICs specifically tailored for automotive infotainment systems. Unlike general-purpose logic ICs, it integrates high-current output stages suitable for direct motor actuation. The BD7966EKV addresses the need for compact, reliable motor control in vehicle-mounted CD/DVD players, reducing board space compared to discrete transistor arrays.

Power Management - Specialized Replacement Considerations

Consult ROHM official documentation for direct cross-references. No public substitute part numbers are confirmed in available sources. Verify functional equivalence if considering alternatives from other manufacturers.
