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.

Over current protection (ISD), Thermal shutdown (TSD) circuit, and Undervoltage lockout (UVLO) circuit.

Package: SSOP20 and QFN24

Fast decay: always 12.5%

Built-in cross conduction protection circuit

•

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.
