Low Noise PWM-based Single Chip Motor Driver IC AN4820FHQ
I
Overview
The AN4820FHQ is a single chip IC incorporating PWM system 3-channel
driver for optical pickup and mechanism driving based on a direct PWM or
pulse width modulation driving system for a spindlemotor driving block.
It is an IC best suited for a notebook personal computer thanks to it slow power
consumption as well as its noise and vibration reduction.
I
Features
G
3-phase full-wave low noise PWM system for a spindle motor driving block
G
Linear input and direct PWM system for all channel (SP +3-channel),
resulting in low power dissipation of the end product
G
Independent power supply pin: Placed the power supply pins for a spindle,
actuators, traverse motor independently.
G
