UNISONIC TECHNOLOGIES CO., LTD BA6220 LINEAR INTEGRATED CIRCUIT www.unisonic.com.tw 1 of 3 Copyright © 2012 Unisonic Technologies Co., Ltd QW-R109-001,C GENERAL USE ELECTRONIC GOVERNOR DESCRIPTION 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 ( V CC= 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. APPLICATION * Radio cassette tape recorders DIP-8 SOP-8 ORDERING INFORMATION Ordering Number Package Packing Lead Free Halogen Free BA6220L-D08-T BA6220G-D08-T DIP-8 Tube BA6220L-S08-R BA6220G-S08-R SOP-8 Tape Reel BA6220L-S08-T BA6220G-S08-T SOP-8 Tube
