TB6600HG 2014-01-30 1 TOSHIBA BiCD Integrated Circuit Silicon Monolithic TB6600HG PWM Chopper-Type bipolar Stepping Motor Driver IC 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 • Single-chip bipolar sinusoidal micro-step stepping motor driver • Ron (upper + lower) = 0.4 Ω (typ.) • Forward and reverse rotation control available • Selectable phase drive (1/1, 1/2, 1/4, 1/8, and 1/16 step) • Output withstand voltage: Vcc = 50 V • Output current: IOUT = 5.0 A (absolute maximum ratings, peak) IOUT = 4.5 A (operating range, maximal value) • 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 TB6600HG Weight: HZIP25-P-1.00F: 7.7g (typ.) HZIP25-P-1.00F
