ACT5026 Datasheet PDF

Aeroflex ACT5026

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. 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 3Ø MOSFET H-Bridge Brushless Motor Internal use +15V Reg Direction Current Command Inputs - FW Rect DC/DC Conv +15V ≤ 70mA...
