When using TA8435H/HQ

Introduction
The TA8435H/HQ controls the PWM to set the stepping motor winding current to a constant current. The
device is a micro-step driver IC used to drive the stepping motor efficiently at low vibration.
1.
Micro-step drive
The TA8435H/HQ drives the stepping motor in micro steps with a maximum resolution of 1/8 of the 2-phase
stepping angle (in 2W1-2-phase mode).
In micro step operation, A-phase and B-phase current levels are set inside the IC so that the composite vector
size and the rotation angle are even. Just inputting clock signals rotates the stepping motor in micro steps.
2.
PWM control and output current setting
(1)
Output current path (PWM control)
The TA8435H/HQ controls the PWM by turning the upper power transistor on and off.
Here, current flows as shown in the figure below.
(2)
Setting of output current by REF-IN input and current detection resistor
The motor current (maximum current for micro-step drive) IO is set as shown in the following
equation, using REF-IN input and the external current detection resistor RNF.
IO = VREF / RNF
where,
REFIN = High,
VREF = 0.8 V
REFIN = Low,
VREF = 0.5 V
