| UNISONIC TECHNOLOGIES CO., LTD BA6208 REVERSIBLE MOTOR DRIVER DESCRIPTION The UTC BA6208 is designed for driving reversible motor use, it contain a logic section to controls forward and reverse rotations as well as forced stop, and an output power section is able to supply an output current of up to 100mA (typical) according to the logic control. The IC allow control of reversible motors in cassette players and other electrical equipment by using TTL-level logic signals. LINEAR INTEGRATED CIRCUIT DIP-8 SIP-9 FEATURES * Recommended operating supply voltage range from 4.5V to15.0V. * Built-in motor driving power transistors(typ.100mA). * Brake is applied when stopping the motor (when Ain and Bin are both HIGH level). * Very low standby circuit current(when Ain and Bin are both LOW level. * Built-in diode to absorb surge currents. * Direct control with the TTL logic. SOP-8 *Pb-free plating product number: BA6208L ORDERING INFORMATION Ordering Number Normal Lead Free Plating BA6208-D08-T BA6208L-D08-T BA6208-G09-T BA6208L-G09-T BA6208-S08-R BA6208L-S08-R BA6208-S08-T BA6208L-S08-T Package DIP-8 SIP-9 SOP-8 SOP-8 Packing Tube Tube Tape Reel Tube BA6208L-D08-T (1)Packing Type (2)Package Type (3)Lead Plating (1) R: Tape Reel, T: Tube (2) D08: DIP-8, G09: SIP-9, S08: SOP-8 (3) L: Lead Free Plating Blank: Pb/Sn , www.unisonic.com.tw Copyright (c) 2005 Unisonic Technologies Co., Ltd 1 of 4 QW-R109-004,C BA6208 PIN CONFIGURATION LINEAR INTEGRATED CIRCUIT For SIP-9 Package 1 NC 2 BIN 3 AIN 4 NC 5 GND 6 Vcc 7 BOUT 8 AOUT 9 NC For SOP-8/DIP-8 Package VCC BOUT GND AOUT 1 BOUT 2 3 4 8 7 6 5 AIN GND NC BIN UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 4 QW-R109-004,C BA6208 ABSOLUTE MAXIMUM RATING (Ta=25C) PARAMETER Power Supply Voltage Maximum Output Current LINEAR INTEGRATED CIRCUIT RATINGS 18 500 DIP-8 500 Power Dissipation PD SIP-9 700 SOP-8 450 Operating Temperature TOPR -20 ~ +60 Storage Temperature TSTG -55 ~ +125 Note Absolute maximum ratings are those values beyond which the device could be permanently damaged.
