Motor Control Circuits
s Overview
The AN6612 and the AN6612S are the electronic gov-
ernor circuits suitable for the rotating speed control of a
low voltage and compact DC motor which is used for a
small tape recorder, etc.
s Features
• Wide range of operating voltage : V_{CC (opr)} =1.8V ~ 8V
• 2 package types
• Fewer external parts
• Speed control in steps with linear fine control
• Output current limiting circuit is built-in
