ACT5026 Description
The ACT5026 bines 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 mand voltage linearly controls the motor current with a scale-factor of 2 Amps per volt and a small-signal bandwidth of 2KHz. Input mand polarity determines Motor direction.
