Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | VIN | power_in | Input to the internal 8.0-450V linear regulator that supplies VDD. Absolute maximum 470V to GND; typical operating range 8.0-450V DC. |+| 2 | CS | input | Current sense input. Senses the external FET current across a sense resistor RCS; when this pin exceeds the lower of the internal 250mV reference or the LD pin voltage, GATE goes low. Blanking interval 150-280ns. |+| 3 | GND | power_in | Ground return for all internal circuitry. Must be electrically connected to the ground of the power train. |+| 4 | GATE | output | Output gate driver for an external N-channel power MOSFET. Sourcing/sinking capability 165mA, rise/fall time 30-50ns into 500pF at VDD=7.5V. |+| 5 | PWMD | input | PWM dimming input. When pulled to GND, the GATE driver is disabled; when pulled high (>=2.0V), GATE operates normally. Internal pull-down of 50-150kΩ. Tie to VDD to disable PWM dimming. |+| 6 | VDD | power_out | Internally regulated 7.5V supply for all internal circuits. Must be bypassed with a low-ESR capacitor (>=0.1µF) to GND. Can be externally driven above the internal regulator voltage but must not exceed 12V. |+| 7 | LD | input | Linear dimming input. Sets the current-sense threshold when the pin voltage is less than 250mV (typ); tie to VDD to use the internal 250mV reference. Accepts a 0-250mV analog control signal for LED current adjustment. |+| 8 | RT | passive | Oscillator timing resistor pin. Resistor from RT to GND sets constant-frequency operation; resistor from RT to GATE sets constant off-time mode. tOSC(µs) = (RT(kΩ)+22)/25. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Microchip |+| Package | SOIC-8 |+| Category | LED-drv |+| Pins | 8 |++## Ordering variants++- `HV9910BLG-GLG-G`+- `HV9910BLG-GNG-G`++## CAD (KiCad official)++- Symbol: `HV9910BLG-G`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Microchip datasheet](docs/hv9910blg-g-datasheet.pdf) (15 pp, sha256 `69b6d679b136d563`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
