GR6405SNS08ARDQ

GR · LED Drivers · SOP-8

GR6405SNS08ARDQ from GR, in a SOP-8. 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	GND	power_in	Power negative (ground) pin for the GR6405S, per the pin function table.
2	FB2	passive	Channel 2 current-setting pin; the external R3 resistor sets the LED2- constant current, with 1 Ω (1%) giving 280-340 mA, 1.5 Ω (1%) giving 200-240 mA and 3 Ω (1%) giving 108-132 mA at VCC = 5 V.
3	FB1	passive	Channel 1 current-setting pin; the external R4 resistor sets the LED1- constant current, with the same resistor-to-current values as channel 2 at VCC = 5 V.
4	LED1-	output	Channel 1 LED negative terminal, which is the constant-current sink; the programmable range is 10 mA to 350 mA.
5	LED2-	output	Channel 2 LED negative terminal, which is the constant-current sink; the programmable range is 10 mA to 350 mA.
6	EN1	input	Channel 1 enable input, active high; at VCC = 5 V it needs VIH of at least 1.5 V and VIL of at most 0.5 V.
7	EN2	input	Channel 2 enable input, active high; at VCC = 5 V it needs VIH of at least 1.5 V and VIL of at most 0.5 V.
8	VCC	power_in	Positive supply pin; the supply voltage must be within 4.5 V to 5.5 V.

CAD (KiCad official)

Symbol: GR6405SNS08ARDQ
Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
3D model: SOP-8 (KiCad packages3D, STEP)
3D model files: gr6405sns08ardq-etched.step / gr6405sns08ardq-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); gr6405sns08ardq.step / gr6405sns08ardq.glb are the bare package body.
