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
