BA6220

UNISONIC TECHNOLOGIES CO., LTD BA6220 GENERAL USE ELECTRONIC GOVERNOR DESCRIPTION The UTC BA6220 is a monolithic integrated circuit, developed for speed control of general use DC motors. LINEAR INTEGRATED CIRCUIT DIP-8 FEATURES * Wide range of working power supply voltage range (VCC= 3.5V - 16V). * Very large starting torque at the low voltage. * Large permissible loss due to effective utilization of substrate radiation. * Usable for various DC motors by means of changing constants of the external components. SOP-8 APPLICATION * Radio cassette tape recorders *Pb-free plating product number: BA6220L ORDERING INFORMATION Order Number Normal Lead Free Plating BA6220-D08-T BA6220L-D08-T BA6220-S08-R BA6220L-S08-R BA6220-S08-T BA6220L-S08-T Package DIP-8 SOP-8 SOP-8 Packing Tube Tape Reel Tube www.unisonic.com.tw Copyright © 2005 Unisonic Technologies Co., Ltd 1 of 3 QW-R109-001,B BA6220 BLOCK DIAGRAM LINEAR INTEGRATED CIRCUIT UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 5 QW-R109-001,B BA6220 ABSOLUTE MAXIMUM RATINGS (Ta=25°C) PARAMETER Supply Voltage Power Dissipation(note 1) DIP-8 SOP-8 LINEAR INTEGRATED CIRCUIT SYMBOL VCC PD Operating Temperature TOPR Storage Temperature TSTG Note 1.
