# HVLED001ATR

**STMicroelectronics** · LED Drivers · SSOP-10-150mil

HVLED001ATR from STMicroelectronics, in a SSOP-10-150mil. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | HVSU | input | High voltage startup and input voltage detection input with 800 V breakdown rating for direct connection to input voltage with series resistor. |
| 2 | N.C. | unconnected | Not connected pin. |
| 3 | TOFF | input | Programmable blanking time selection input for zero voltage detection; minimum blanking obtained when pin left unconnected. |
| 4 | FB | input | Feedback regulation input for optocoupler or compensation network with 0.3 to 3.6 V operating range; VOFP threshold detects optocoupler failure. |
| 5 | CTRL | input | IC disable and soft-start ramp control input with 0 to VCC operating range; external active circuitry can turn off application. |
| 6 | ZCD | input | Multi-function zero current detection and output voltage sensing input with -0.3 to 7 V range; negative-going edge triggers MOSFET turn-on. |
| 7 | CS | input | Current sense comparator input with 0.3 to 7 V operating range; second-level overcurrent threshold detects abnormal currents. |
| 8 | GND | power_in | Ground reference pin. |
| 9 | GD | output | Gate driver output with 0.3 to VCC V swing capability for driving power MOSFETs and IGBTs. |
| 10 | VCC | power_in | IC supply voltage input rated from startup threshold to 18 V maximum with internal UVLO logic and clamp protection; requires 10 µF bulk and 100 nF ceramic capacitors to GND. |
