Motors or sensors, such as a Hall device, are not required by the starting circuit for self-starting, or for performing position detection by BEMF. As the output stage of all channels works in efficient PWM driving, low- power operation by PWM control is possible. Neutral zone-less control is possible for a focus / tracking / tilt actuator driver. In addition, the spindle part output current limiting circuit, thermal shutdown circuit, sled-end detection circuit, collimator lens end detection circuit, actuator protection, and three beam laser drivers are built in. The newly added built-in thermometer can measure IC temperature. 6 Pin Configuration and Functions DFD Package 56-Pin HTSSOP Top View Copyright © 2015, Texas Instruments Incorporated Submit Documentation Feedback 3 Product Folder Links: TPIC2050 |
