UNISONIC TECHNOLOGIES CO., LTD BA6220 LINEAR INTEGRATED CIRCUIT GENERAL USE ELECTRONIC GOVERNOR DESCRIPTION DIP-8 The UTC BA6220 is a monolithic integrated circuit, developed for speed control of general use DC motors. 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 ORDERING INFORMATION Ordering Number Lead Free Halogen Free BA6220L-D08-T BA6220G-D08-T BA6220L-S08-R BA6220G-S08-R BA6220L-S08-T BA6220G-S08-T www.unisonic.com.tw Copyright © 2012 Unisonic Technologies Co., Ltd Package Packing DIP-8 SOP-8 SOP-8 Tube Tape Reel Tube 1 of 3 QW-R109-001,C BA6220 LINEAR INTEGRATED CIRCUIT PIN CONFIGURATION GND 1 8 GND 2 7 GND GND 3 6 GND VR 4 5 OUT VCC BLOCK DIAGRAM GND 1 8 OUT GND 2 7 GND GND 3 6 GND VR 4 5 VCC STARTER UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw VREF 2 of 5 QW-R109-001,C BA6220 LINEAR INTEGRATED CIRCUIT ABSOLUTE MAXIMUM RATINGS (TA=25℃, unless otherwise specified.)
