Capable of delivering peak output currents up to 5A, the TB6600HQ is a single chip, PWM chopper-type, bipolar, micro-step stepping motor driver from Toshiba Electronics. According to the company, it will reduce component count in industrial systems, office automation equipment, or wherever accurate, repeatable, maintenance-free operation is required. The driver has forward and reverse rotation control and selectable 1/1, 1/2, 1/4, 1/8 and 1/16 step resolution. A sinusoidal output supports low-vibration, high-efficiency motor operation. There is a choice of phase drives which can be selected, according to the design requirements. The integrated device incorporates PWM generation and encoding circuitry, a single clock signal is all that is needed for the automatic generation of the sinusoidal micro-step waveform.
