Overview

The LB11699H is a spindle motor driver IC for CD-ROM drives.

Features

• Three-phase brushless motor driver

Functions

• Current linear drive

• Voltage controlled amplifier

• The use of high side current detection means that there is no loss (or voltage drop) due to the current detection resistor.

• Built-in short-circuit braking circuit

• Built-in reverse rotation prevention circuit

• Hall sensor FG output

• Built-in start/stop function

• Built-in current limiter circuit (adjustable)

• Built-in Hall sensor power supply

• Built-in thermal shutdown circuit

• Supports 3.3V DSPs

• Maximum current rating: 2.0A
