TB6560AFTG TOSHIBA BiCD Integrated Circuit Silicon Monolithic TB6560AFTG PWM Chopper-Type Bipolar Driver IC for Stepping Motor Control The TB6560AFTG is a PWM chopper-type stepping motor TB6560AFTG driver IC designed for sinusoidal-input microstep control of bipolar stepping motors. The TB6560AFTG can be used in applications that require 2-phase, 1-2-phase, 2W1-2-phase and 4W1-2-phase excitation modes. The TB6560AFTG is capable of low-vibration, high-performance forward and reverse driving of a two-phase bipolar stepping motor using only a clock signal. Features Weight: 0.137g (typ.) 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) = 0.7 (typ.) Forward and reverse rotation Selectable phase excitation modes (2, 1-2, 2W1-2 and 4W1-2) High output withstand voltage: V = 40 V DSS High output current: I = 2.5 A (peak) OUT Packages: QFN48-P-0707-0.50 Internal pull-down resistors on inputs: 100 k (typ.) Output monitor pin: M current (I (max) = 1 mA) O MO Reset and enable pins Thermal shutdown (TSD) *: These ICs are highly sensitive to electrostatic discharge. When handling them, ensure that the environment is protected against electrostatic discharge. Ensure also that the ambient temperature and relative humidity are maintained at reasonable level. *Solderability 1.
