Description

The AT78C7005 is a CMOS monolithic device that integrates Spindle and VCM controllers as well as power stages into one chip. The device operates from 3.3V or 5V power supply. The AT78C7005 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 AT78C7005, differential input current sense amplifier, ramp load/unload capability, and power output amplifier.
