BD8271EFV - 3ch System Motor Driver

General Description

BD8271EFV is 3ch power driver developed for driving stepper motor and DC motor (or actuator coil).

Blu-ray’s motor & coil can be driven, when used along with 6ch DVD power driver.

Power Supply Voltage Operating Temperature Range Output On Resistance (SLED)

Key Features

  • Each driver of SLED (2ch) and Actuator (1ch) are installed in a single-chip. ON/OFF and the standby mode of 3ch can be selected using two control terminals. Built-in triangular wave generator circuit. Adopts HTSSOP-B24 package that has high power dissipation. Built-in thermal shutdown function. Highly effective SLED driver with PWM drive system. Built-in 2ch SLED driver that corresponds to the stepper motor drive. The actuator driver is linear BTL.
