GND The center frame (FR) functions as a power system GND. Set it to the minimum potential together with S-GND. 2. Bypass capacitor For power supply, connect the bypass capacitor immediately near the pin of this IC. 3. Lightening, ground fault, and short-circuit between outputs Avoid short-circuit between the output pin and power supply (lightening), short-circuit between the output pin and GND (ground fault), and short-circuit between output pins (load short-circuit). When mounting IC to the substrate, pay attention to the direction of IC. Mounting in the wrong direction may cause damage to IC, and fuming in certain cases.
