TB6560AHQ/AFG
TOSHIBA BiCD Integrated Circuit Silicon Monolithic
TB6560AHQ, TB6560AFG
PWM Chopper-Type Bipolar Driver IC for Stepping Motor Control
The TB6560AHQ/AFG 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.
TB6560AHQ
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) =
TB6560AHQ: 0.6 Ω (typ.)
TB6560AFG: 0.7 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 = TB6560AHQ: 3.5 A (peak)
TB6560AFG: 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)
TB6560AFG
Weight
HZIP25-P-1.27: 9.86 g (typ.)
HQFP64-P-1010-0.50: 0.26 g (typ.)
*Solderability
1. Use of Sn-37Pb solder bath
*solder bath temperature = 230°C
*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 = 245°C
*dipping time = 5 seconds
*the number of times = once
*use of R-type flux
*: 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.

Relationship between the Enable and RESET and Output Signals
Example 1: ENABLE input in 1-2-phase excitation mode (M1: H, M2: L)

OFF
t7 t8 t9 t10 t11 t12
Setting the ENABLE signal Low disables only the output signals, while internal circuitry other than the
output block continues to operate in accordance with the CLK input. Therefore, when the ENABLE signal goes
High again, the output current generation is restarted as if phases proceeded with the CLK signal.
Example 2: RESET input in 1-2-phase excitation mode (M1: H, M2: L)

Setting the RESET signal Low causes the outputs to be put in the Initial state and the MO output to be
driven Low (Initial state: A-channel output current is at its peak (100 %)).
When the RESET signal goes High again, the output current generation is restarted at the next rising edge
of CLK with the state following the Initial state.
