1 / 12 page  CIRCUIT TECHNOLOGY www.aeroflex.com eroflex Circuit T echnology – Motor Driver Modules For The Future © SCD5101-1 REV D 5/14/01 Features • 500 VDC RATING • 40 AMP CONTINUOUS CURRENT (UP TO 85°°°°C) • PACKAGE SIZE 3.0" X 2.1" X 0.39" • 4 QUADRANT CONTROL • 6 STEP TRAPEZOIDAL DRIVE CAPABILITY • MILITARY PROCESSING AVAILABLE • MIL-PRF-38534 COMPLIANT CIRCUITS AVAILABLE • ISOLATED UPPER AND LOWER GATE DRIVERS • FULL MILITARY (-55°C TO +125°C) TEMPERATURE RANGE General Description The ACT5101-1 high voltage 3 phase brushless DC motor drive combines a 500 VDC, 40A high power output stage along with low power digital input and gate drive stages. A digital lock-out feature protects the output stage from accidental cross-conduction thus preventing shoot-through conditions. The ACT5101-1 also includes a floating gate drive design for each upper and lower transistor. On-board gate drive supplies provide a continuous floating voltage for each upper and lower transistor, even during a motor stall. The high power output stage rated at 500 VDC, 40A is capable of delivering over 20 kW to the load even after derating. This is accomplished through the use of high power IGBTS with ultra-fast recovery rectifiers in parallel. The ACT5101-1 utilizes power hybrid technology to provide the highest levels of reliability and lightest weight while requiring the smallest amount of board space. The ACT5101-1 is available with military processing and operates over the full -55 to +125 degrees C temperature range. This makes the ACT5101-1 ideal for all military, space,and commercial avionics' applications. These incl- ude electro-hydrostatic actuators [EHA's] and electro-mechanical actuators [EMA's] for flight surface control, missile fin actuators, thrust vector control, electric brakes, fuel and cooling pumps.
