TOSHIBA BiCD Integrated Circuit Silicon Monolithic
TB6600HG
PWM Chopper-Type bipolar
Stepping Motor Driver IC
TB6600HG
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.

Description of Functions
1. Excitation Settings
The excitation mode can be selected from the following eight modes using the M1, M2 and M3 inputs. New
excitation mode starts from the initial mode when M1, M2, or M3 inputs are shifted during motor operation.
In this case, output current waveform may not continue.

( 0%, 100% )

HH
Standby mode
H
(Operation of the internal circuit is almost turned off.)
Note: To change the exciting mode by changing M1, M2, and M3, make sure not to set M1 = M2 = M3 = L or M1 = M2 =
M3 = H.
Standby mode
The operation mode moves to the standby mode under the condition M1 = M2 = M3 = L or M1 = M2 = M3
= H.
The power consumption is minimized by turning off all the operations except protecting operation.
In standby mode, output terminal MO is HZ.
Standby mode is released by changing the state of M1=M2=M3=L and M1=M2=M3=H to other state.
Input signal is not accepted for about 200 μs after releasing the standby mode.
