7 / 26 page STK672-440B-E No.A1734-7/24 • Motor current peak value IOH setting [Smoke Emission Precuations] If Pin 18 (S.G terminal) is attached to the PCB without using solder, overcurrent may flow into the MOSFET at VCCON (24V ON), causing the STK672-440B-E to emit smoke because 5V circuits cannot be controlled. Function Table M2 0 0 1 1 M1 M3 0 1 0 1 CLOCK Edge Timing for Phase Switching 1 2-phase excitation selection 1-2-phase excitation (IOH=100%) W1-2 phase excitation 2W1-2 phase excitation CLOCK rising edge 0 1-2 phase excitation (IOH=100%, 71%) W1-2 phase excitation 2W1-2 phase excitation 4W1-2 phase excitation CLOCK both edges IOH=100% results in the Vref voltage setting, IOH. During 1-2 phase excitation, the hybrid IC operates at a current setting of IOH=100% when the CLOCK signal rises. Conversely, pseudo micro current control is performed to control current at IOH=100% or 71% at both edges of the CLOCK signal.
