TB6560AHQ TB6560

Układ TB6560AHQ sterownik silnika krokowego.

The TB6560AHQ is a PWM chopper-type stepping motor driver IC designed for sinusoidal-input microstep control of bipolar stepping motors. The TB6560AHQ/AFG can be used in applications that require 2-phase, 1-2-phase, 2W1-2-phase and 4W1-2-phase excitation modes. The TB6560AHQ/AFG is capable of low-vibration, high-performance forward and reverse driving of a two-phase bipolar stepping motor using only a clock signal.

Features • Single-chip motor driver for sinusoidal microstep control of stepping motors • High output withstand voltage due to the use of BiCD process: Ron (upper and lower sum) = 0.6 Ω (typ.) • Forward and reverse rotation • Selectable phase excitation modes (2, 1-2, 2W1-2 and 4W1-2) • High output withstand voltage: VDSS = 40 V • High output current: IOUT = AHQ: 3.5 A (peak) AFG: 2.5 A (peak) • Packages: HZIP25-P-1.27 HQFP64-P-1010-0.50 • Internal pull-down resistors on inputs: 100 kΩ (typ.) • Output monitor pin: MO current (IMO (max) = 1 mA) • Reset and enable pins • Thermal shutdown (TSD)
