Sample Application Circuit
Cautions:
• V CC and GND lines suffer substantial fluctuation in the current quantity, causing a problem of line oscillation in
certain cases. In this case, take following points into account:
(1) Use a thick and short wiring to reduce the wiring inductance.
(2) Insert a capacitor with satisfactory frequency characteristics near IC.
(3) Connect S-GND to the control system GND on the CPU side and P-GND to the power system GND.
