GENERAL DESCRIPTION

Overview

The OM5193H is a combination of a voice coil motor and a spindle motor driver with embedded servo controller designed for use in disk drives. Configuration and control registers are set via a 3-wire serial port running up to 30 MHz to interface commonly to a microcontroller or a digital signal processor.

The device operates at 5 and 12 V power supplies and integrates safety functions such as power stages overvoltage protection, power and temperature monitor, over-temperature shutdown and dynamic brake-after-park.

The device is contained in a QFP80 package with 18 pins connected to the leadframe thus providing low thermal resistance.

FEATURES

Servo control

? 10-bit VCM Digital-to-Analog Converter (DAC)

? 7-channel 10-bit Analog-to-Digital Converter (ADC)

? Programmable spindle commutation control logic

? 3-wire serial interface

? Two stand-alone operational amplifiers (op-amps) with outputs connected to the ADC

? Analog multiplexer with two inputs used to select VCM seek mode or track-following mode.
