Overview
The BD7763EFV-E2 is a system motor driver IC manufactured by ROHM Semiconductor, designed for half-height drive applications such as Blu-ray drives. It operates within a supply voltage range of 4.3 V to 13.2 V and features nine output channels with current capabilities of 500 mA and 1 A. The device integrates control logic with MOSFETs and functions at a maximum operating temperature of +75°C and minimum of -20°C. It dissipates up to 2 W of power and is housed in a 54-pin HTSSOP-B package.
Feature Summary
- Integrates control logic with internal MOSFETs for compact system motor driving
- Provides nine dedicated output channels for multi-motor or actuator control
- Designed specifically for sensorless half-height drive applications
Applications
- Blu-ray drive systems
- Half-height optical disc drive mechanisms
- Multi-actuator motor control circuits
Procurement Notes
This component is officially listed as obsolete and production has been terminated by the manufacturer. It is not available for new sales orders. Verify end-of-life status through official ROHM channels before finalizing design specifications. Sourcing may only be possible through secondary market distributors, subject to availability and authenticity verification.
Selection Notes
Select this part only for legacy designs requiring a nine-channel system motor driver for half-height drives. The limited thermal performance (+75°C max) and specific voltage range restrict usage in high-power or wide-temperature environments. Ensure the application does not require active cooling or extended industrial temperature ratings.
Part Context
The BD7763EFV-E2 belongs to ROHM’s system motor driver family, optimized for consumer electronics like optical disc drives. It consolidates multiple driver stages into a single HTSSOP-B package to reduce board space. As an obsolete product, it represents a previous generation of integrated motor control solutions for compact media devices.
Replacement Considerations
No public confirmed substitute part numbers are documented. Designers must evaluate newer ROHM motor driver series or generic alternatives based on pin compatibility and electrical requirements.
