The AN6652 is an IC designed for the rotating speed control of a compact DC motor which is used for a tape recorder, record player, etc. n Features

• Small four-lead plastic package for compact motor. Fewer external parts
• Stable low reference voltage (1.25V typ.), wide motor speed setting
• Highly stable operation over a wide range of supply voltage and torque supply voltage, VCC = 6V ~ 20V
• Reverse voltage protection circuit is built-in AN6652 Motor Control Circuit Unit : mm 11.5max.15.0min. 8.0 + 0.5 – 0.1 3.05 3.81.94 12 3 4 0.5–0.2 4-Lead SIP Package (SSIP004-P-0000) 1.778 1.778 5.334 1234 3.5max. 0.5–0.1 1.44 1.76 1.778 GND COM 2 3 41 × 20 (K) MotorControlV CC V REF n Block Diagram n Pin Descriptions Pin No. Pin Name V CC Control Pin GND Motor Pin
