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. Use of Sn-37Pb solder bath
*solder bath temperature = 230C
*dipping time = 5 seconds
*number of times = once
*use of R-type flux
2. Use of Sn-3.0Ag-0.5Cu solder bath
*solder bath temperature = 245C
*dipping time = 5 seconds
*the number of times = once
*use of R-type flux
