AW36404DNR

AWINIC(Shanghai Awinic Tech) · LED Drivers · DFN-8-EP(1.5x1.5)

AW36404DNR from AWINIC(Shanghai Awinic Tech), in a DFN-8-EP(1.5x1.5). 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 AGND power_in Analog ground pin, to be connected directly to a large PCB ground plane for thermal and noise performance.
2 LED output Low-side current sink output driving the LED, with 400 mA maximum flash/torch current and dropout of 100 mV typical (160 mV maximum) at 400 mA.
3 NC unconnected No connect; this pin can be left floating or connected to AGND.
4 PGND power_in Power ground pin, to be connected to a large PCB ground plane for thermal performance.
5 VIN power_in Power supply input with an operating range of 2.7 V to 5.5 V; the input capacitor should be placed close to this pin.
6 NC unconnected No connect; this pin can be left floating or connected to AGND.
7 FLASH/TORCH input Mode select: high selects flash mode with 1.2 s typical timeout, low selects torch mode with timeout disabled; internal 500 kΩ pull-down.
8 EN input Enable pin: LED current is set by counting 1-wire pulses (64 steps, 400 mA maximum), and EN low for longer than 2.5 ms shuts the device down; internal 500 kΩ pull-down.
9 PGND power_in Power ground pin, to be connected to a large PCB ground plane for thermal performance.

CAD (KiCad official)

  • Symbol: AW36404DNR
  • Footprint: Package_DFN_QFN:DFN-8-1EP_1.5x1.5mm_P0.4mm_EP0.7x1.2mm
  • 3D model: DFN-8-EP(1.5x1.5), generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.55 mm nominal QFN height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: aw36404dnr-etched.step / aw36404dnr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); aw36404dnr.step / aw36404dnr.glb are the bare package body.
