ACT5026 10 AMP 3-PHASE BRUSHLESS DC MOTOR CONTROLLER Features s s s s s s s s s Preliminary CIRCUIT TECHNOLOGY www.aeroflex.com V Supply 28V to 40V 10 Amps Continuous Current (Up to 85C) Package Size 1.7" x 1.3" x 0.275" 4 Quadrant Control 3 Phase Commutational Logic 15VDC Regulators for External & Internal Use Military Processing Available MIL-PRF-38534 Compliant Circuits Available Full Military (-55C to +125C) Temperature Range General Description The ACT5026 combines a high power MOSFET 3 phase H-bridge output stage with all of the control circuitry required to form a closed loop motor controller. The input command voltage linearly controls the motor current with a scale-factor of 2 Amps per volt and a small-signal bandwidth of 2KHz. Input command polarity determines Motor direction. Only one supply is necessary due to the internal regulators and converter which provide 15 Volts for internal as well as external use. The circuitry includes: * Fully Differential Input Amplifier * A Pulse Width Modulator Internally clocked at 16.7KHz (Has external Sync pin) * 15 Volt regulated outputs derived from main supply * Internal Current Sense Resistor * External Loop Compensation pins to tailor to specific motors * Current Monitor Output with Scale Factor of 1.67 Volts/Amp 16.7 KHz Clock (Optional) SYNC Cktry BLOCK DIAGRAM OSC V Supply Hall Inputs PWM PWM Input External Loop Comp + Logic 3O MOSFET H-Bridge Brushless Motor Internal use +15V Reg Direction Current Command Inputs - FW Rect DC/DC Conv +15V 70mA Internal use Current Monitor FW Rect Current Sense -15V Reg -15V 20mA V RTN eroflex Circuit Technology - Motor Driver Modules For The Future (c) SCD5026 REV A 8/21/98 Z CIRCUIT TECHNOLOGY Package Outline Drawing 2.200 1.950 1.700 .250 .010 O.125 .275 MAX .600 .020 .045 (2 Holes) 1.300 ACT 5026 88379 MADE IN U.S.A.
