DESCRIPTION
The L6243/D is a Bipolar IC developed for use in
Hard Disk Head Actuator positioning applications.
The Power Op-Amp Output Bridge, Differential
Amplifier, and Error Amplifier, are controlled by
TTL/CMOS, input compatible, Digital Logic, and
an Analog Current Control Voltage. A simple
RC compensation network, tied to the output of
the Error Amp, will configure the system to work
as a Transconductance Amplifier to drive a
Voice Coil Motor in LinearMode.
Additional features include Power On Reset De-
lay, Enable and Park, as well as a general pur-
pose Operational Amplifier. A logic low at the
Park input activates the parking function. Holding
the Enable input low will disable the device by
forcing the outputs into a tristate mode. Power
Fail Monitors for the logic and power supplies in-
itiate an automatic parking sequence during a
power failure. A resistor programmed parking
voltageenables a constantvelocityhead retract.
