The TB6600HG is a PWM chopper-type single-chip bipolar sinusoidal micro-step stepping motor driver

Forward and reverse rotation control is available with 2-phase, 1-2-phase, W1-2-phase, 2W1-2-phase, and 4W1-2-phase excitation modes.

2-phase bipolar-type stepping motor can be driven by only clock signal with low vibration and high efficiency.

Features:

• Packages: HZIP25-P-1.00F
• Built-in input pull-down resistance: 100 kΩ (typ.), (only TQ terminal: 70ｋΩ(typ.))
• Output monitor pins (ALERT): Maximum of IALERT = 1 mA
• Output monitor pins (MO): Maximum of IMO = 1 mA
• Equipped with reset and enable pins
• Stand by function
• Single power supply
• Built-in thermal shutdown (TSD) circuit
• Built-in under voltage lock out (UVLO) circuit
• Built-in over-current detection (ISD) circuit
