Description
The AT78C7015 is a CMOS monolithic device that integrates Spindle and VCM con-
trollers as well as power stages into one chip. The device operates from 3.3V power
supply. The AT78C7015 is designed for a small-form-factor hard disk drive application.
A precision low-voltage detection circuit monitors the power supply and initiates VCM
retract at voltage fault condition. A 3-line serial port interface with read back capability
provides interface to the microprocessor.
The Spindle driver features a transconductance amplifier, a current sense amplifier,
power output drivers, sequencer, internal delay/masking logic, Spindle brake circuit,
FLL, and charge-pump for locking the spindle to the programmed rotational speed.
The VCM driver features a transconductance amplifier, differential input current sense
amplifier, ramp load/unload capability, and power output amplifier.
