TC78S600FNG/FTG
Stepping Motor Driver IC
The TC78S600FNG/FTG is a PWM constant-current type
stepping motor driver IC designed for sinusoidal-input
micro-step control of stepping motors.
The TC78S600FNG/FTG can be used in applications that
require 1-2-phase, W1-2-phase, 2W1-2 phase, and 4W1-2 phase
excitation modes. The TC78S600FNG/FTG is capable of forward
and reverse driving of a 2-phase bipolar stepping motor using
only a clock signal.

This product has a MOS structure and is sensitive to electrostatic discharge. When handling this product, ensure
that the environment is protected against electrostatic discharge by using an earth strap, a conductive mat and an
ionizer. Ensure also that the ambient temperature and relative humidity are maintained at reasonable levels.
Do not insert devices in the wrong orientation or incorrectly. Otherwise, it may cause the device breakdown,
damage and/or deterioration.
