When a circuit using the INX IN518 fails, the pinout diagram becomes your diagnostic map.
If you are troubleshooting a blank screen, vertical lines, or power issues, understanding the IN518’s pinout is critical. Inx In518 Ic Pinout Diagram
Capable of delivering up to 2A or 3A of continuous output current. When a circuit using the INX IN518 fails,

You have the SOP-20 variant. Pins 19 and 20 are additional power/ground or test pins. Refer to the manufacturer’s addendum – many are no-connects or must be tied to VSS.
Fix: Measure the voltage directly at Pin 5 (EN). If it is floating or drops below the logical threshold voltage (usually under 0.4V), the chip will remain entirely disabled.
