Pin Function Grouping
Looking at the datasheet of this component, can you group together pins by their functions? for example for Power, VDD, gnd etc
NOTE: If you group them, can you not add the same pin if you already added them in a group? You should know which pin function is common for its function

I grouped each Hi5000Q pin into exactly one functional group—Power/Supply, Ground/Thermal Return, Current Sense, Gate Drive, Dimming/Control, Feedback/Protection, and Compensation/Filtering—without duplicating any pin across groups. Full grouping is in the Hi5000Q Pin Functional Groups project file.

Hi5000Q Pin Functional Groups
Source used: current project terminals and their Pin Number properties. Grouping rule applied: each pin is assigned to exactly one functional group; no duplicate pin membership.
Proposed groups
Table
| Functional group | Pins | Why grouped here |
|---|---|---|
| Power / Supply | 15 VIN; 10 VDD | VIN is the main input supply; VDD is the IC internal/supply rail pin. |
| Ground / Thermal Return | 4 GND; 5 GND; 6 GND; 17 GND | Ground/reference pins, including the exposed/thermal pad if pin 17 is the package pad. |
| Current Sense | 16 ISENSEP; 1 ISENSEN; 13 CS | Differential LED/output current sense and current-limit/sense-related input pins. |
| Gate Drive / Power Switch Control | 14 GATE | External MOSFET gate-drive output. |
| Dimming / Enable Control | 3 PWM; 12 DIM; 11 LD | User/control inputs related to PWM dimming, analog dimming, and linear-dimming/load-control behavior. |
| Regulation Feedback / Protection | 9 VFB; 2 UVLO | Feedback and supply undervoltage lockout/protection sensing. |
| Compensation / Filtering | 7 COMP; 8 CLPF | Loop compensation and control/filter capacitor pins. |

| 12 | DIM | Dimming / Enable Control |
| 13 | CS | Current Sense |
| 14 | GATE | Gate Drive / Power Switch Control |
| 15 | VIN | Power / Supply |
| 16 | ISENSEP | Current Sense |
| 17 | GND | Ground / Thermal Return |
Notes
- I intentionally did not place any pin in more than one group.
- For Flux terminal properties, these would map well to:
- Section = Power for VIN and VDD
- Section = Ground for GND pins
- Section = Signal or Analog for ISENSEP/ISENSEN/CS/VFB/COMP/CLPF/UVLO
- Section = Control for PWM/DIM/LD
- Section = Signal or Output for GATE
- If you want, I can also apply these group/section properties directly to the terminal components in this part project.
