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. |
