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.  
Features  
Motor power supply voltage: VM = 15V (max)  
Control power supply voltage: Vcc = 2.7 to 5.5V (operation  
range)  
Output current: Iout 0.8A (max)  
P-WQFN24-0404-0.50-004  
Output ON-resistance: Ron = 1.2Ω (upper and lower sum)  
Decoder that enables micro step control with the clock signal  
Weight: SSOP20-P-225-0.65A 0.09g(typ.)  
P-WQFN24-0404-0.50-004 0.03g(typ.)  
Selectable phase excitation modes (1-2, W1-2, 2W1-2, and  
4W1-2)  
Internal pull-down resistors on inputs: 200 kΩ (typ.)  
Output monitor pin ( MO  
)
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.
