PWM Chopper-Type bipolar
Stepping Motor Driver IC
The TB6560HQ/FG is a PWM chopper-type sinusoidal micro-step
bipolar stepping motor driver IC.
It supports both 2-phase/1-2-phase/W1-2-phase/2W1-2-phase
excitation mode 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.
TB6560HQ

The TB6560HQ/FG is a Pb-free product.
The following conditions apply to solderability:
*Solderability
1. Use of Sn-63Pb 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
*: Since this product has a MOS structure, it is sensitive to electrostatic discharge. These ICs are highly sensitive to
electrostatic discharge. When handling them, please be careful of electrostatic discharge, temperature and
humidity conditions.
