| M52461GP SERVO MOTER MOTROL FOR RADIO CONTROL REJ03F0006-0100Z Rev.1.00 Jul.25.2003 Description The M52461GP is a semiconductor integrated circuit for servo control applications. Features Excellent power supply stability and temperature stability Simple setting of dead of band range Small outline (16pin SSOP) Applications Digital proportional systems for radio control, servo motor control ,etc Recommended Operating Conditions Supply Voltage range : 2.8 to 7.5 V Operating temperature : -20 to 75C Input rise time : 500 nS max. Input fall time : 500 nS max. Block Diagram INPUT Control logic circuit Flip - flop Output control One-shot multivibrator Pulse stretcher Voltage regulating circuit VREG Rev.1.00, Jul.25.2003, page 1 of 7 M52461GP Pin Arrangement VREG INPUT Outline :16P2E-A ( 0.65mm p itch) Pin Description Pin No. 1 Symbol VREG Function Regulated voltage source Descriptions This is output of the internal regulated supply voltage. Make connections from this pin to pot-entiometer and pulse stretcher resister. Connect the capacitor and resistor of the pulse stretcher section. Connect the capacitor and band can be changed according the value of this capacitor. Connect a capacitor that will determine the constant current value of pin 6. Constant current will became 100 A at the time of the resistance of 18 k Connect a capacitor that will adjust a triangular wave made by charging of constant current. Connect to the potentiometer for the position detection connected with the output axis. Grounding Connect to the base of the external NPN transistor Connect to the base of the external PNP transistor Connect to the base of the external NPN transistor Connect to the base of the external PNP transistor Connect a capacitor of more than 10 F. Connect a capacitor that will determine the fixed driving pulse width. 2 3 4 5 CST CDB INPUT RT Stretcher pin Dead band setting pin Input pin Constant setting pin 6 7 8 9 10 11 12 13 14 15 16 CL N.C.
