| FUJITSU SEMICONDUCTOR DATA SHEET DS04-29113-4E ASSP BIPOLAR 1A Motor Drive IC for Motor Applications MB3853 s DESCRIPTION The FUJITSU MB3853 is a motor drive IC with two power driver channels capable of sink/source operation, for use in two-channel independent operation or H-type drive operation. The control system and output system have independent power supplies, allowing the control system to be set to low-voltage operation to conserve power. Protective circuits are provided for temperature, overvoltage, and overload current, with an open collector type monitoring terminal. The MB3853 is designed for use with motors in AV products, office automation products, or cameras, and is also an ideal IC for use in automated vending equipment and other unmanned operating devices. s FEATURES * Circuit configuration Two sets of built-in control circuits and power circuits Built-in fly-back diode * Functions Can drive two motors independently or in H-type drive configurations Built-in inhibitor function s PACKAGE w w w .D t a S a e h t e U 4 .c m o (Continued) Plastic SIP, 9 pins (SIP-9P-M02) w w w .D at Sh a et e 4U . om c MB3853 (Continued) * Input/output terminals Power supply terminals : Independent control system supply terminal and output system supply terminal Control terminals : TTL level/CMOS level compatible Monitor terminal : Open collector type * Space-saving package (SIP9) s PIN ASSIGNMENT (FRONT VIEW) VCC1 IN1 IN2 OUT2 GND OUT1 INH VCC2 MONITOR 1 2 3 4 5 6 7 8 9 (SIP-9P-M02) s PIN DESCRIPTION Pin no. 1 2 3 4 5 6 7 8 9 Symbol VCC1 IN1 IN2 OUT2 GND OUT1 INH VCC2 MONITOR I/O I I O O I O Description Control system power supply terminal Load control signal input terminal 1 Load control signal input terminal 2 Load control output terminal 2 Ground terminal Load control output terminal 1 Inhibitor signal input terminal Output system power supply terminal Protective circuit motor signal output terminal (open collector type terminal) 2 MB3853 s BLOCK DIAGRAM VCC1 1 VCC2 8 INH 7 Power supply circuit (ON/OFF) IN1 2 6 OUT1 IN2 3 4 OUT2 Temperature protection circuit 9 MONITOR (open collector terminal) Overvoltage protection circuit Overload current protection circuit Timer circuit 5 GND 3 MB3853 s FUNCTIONAL DESCRIPTION The MB3853 provides two methods for controlling motors.
