TB6564AHQ(THB6064AH)
TOSHIBA BiCD Integrated Circuit Silicon Monolithic
TB6564AHQ (THB6064AH)
PWM Chopper-Type bipolar
Stepping Motor Driver IC
The TB6564AHQ(THB6064AH) is a PWM chopper-type
sinusoidal micro-step bipolar stepping motor driver IC.
It supports 8 kind of excitation modes and forward/reverse mode
and is capable of low-vibration, high-performance drive of
2-phase bipolar type stepping motors using only a clock signal.

Built-in thermal shutdown(TSD) and over-current detection(ISD) circuit
The TB6564AHQ(THB6064AH) is a Sn-Ag plated product including Pb.
The following conditions apply to solderability:
*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.
