The BD7755RFV-E2 from ROHM Semiconductor is a System Motor Driver IC specifically developed for the spindle motor, actuator coil, tilt coil, stepping motor, SA stepping motor, and loading motor drive in desktop Blu-ray drives and recorders. It features a sensorless drive system for the spindle motor, eliminating the need for hall sensors and simplifying wiring. The IC incorporates a low rotation mode for stable low-speed operation and uses PWM control for efficient spindle, stepping, and SA stepping motor drive.
The actuator, tilt, and loading drivers utilize a linear BTL drive system to minimize noise. The BD7755RFV-E2 is housed in an HTSSOP package, which improves heat radiation efficiency. It supports various power supply voltages, with a maximum power supply voltage of 15V for POWER MOS and Preblock/BTL power blocks, and 7V for the PWM control block.
Key features include built-in thermal-shutdown protection and selectable control terminals for ON/OFF functions, brake mode, and standby mode. This IC is ideal for applications requiring precise motor control in optical disc drives.
