Use a temperature of approximately 280°C for 15–20 seconds to reflow the solder without damaging the chip or warping the board.
Ground reference. Connects directly to the system ground plane with a wide trace to minimize loop impedance. FB
Delivers the processed signal or regulated power to the load, such as an external MOSFET or display panel. Inx In518 Ic Pinout Diagram
The IN518 IC works inside tight power margins to drive both small-scale medical devices and large consumer television modules. According to the manufacturer data sheets found on Scribd's IN518 Reference Document , the component operates under a distinct subset of parameters:
| Pin Number | Pin Name | Description / Function | | :--- | :--- | :--- | | | Input 1 | Signal Input for Driver 1 | | 2 | Input 2 | Signal Input for Driver 2 | | 3 | Input 3 | Signal Input for Driver 3 | | 4 | GND | Ground (0V) | | 5 | Output 3 | Corresponding Output for Input 3 | | 6 | Output 2 | Corresponding Output for Input 2 | | 7 | Output 1 | Corresponding Output for Input 1 | | 8 | VCC | Supply Voltage (Check datasheet for max rating) | Use a temperature of approximately 280°C for 15–20
The common return path for power and signals; must be tied to the system ground.
Include:
– Look at the TV/monitor board. Common markings near IN518:
The compact spacing between contacts makes the INX IN518 highly vulnerable to specific field anomalies. Technicians can execute standard diagnostic steps to determine if a chip requires structural rework: FB Delivers the processed signal or regulated power
The INX IN518 typically comes in a or a 20-pin Small Outline Package (SOP-20) . Below is the most commonly referenced pinout for the DIP-18 variant found in industrial LCD controllers.
Usually packaged in surface-mount formats like SOP-8, MSOP-8, or QFN to maximize PCB space savings.
