EG7335B

EG Micro · LED Drivers · SOP-8

EG7335B from EG Micro, 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 VDD power_in Supply pin with an operating range of 2.5 V to 5.5 V (3.7 V typical) and an absolute maximum of -0.3 V to 5.7 V.
2 OPT1 input Mode-select input 1, which together with OPT2 selects one of four operating modes and must be tied to VDD or GND.
3 OPT2 input Mode-select input 2, which together with OPT1 selects one of four operating modes and must be tied to VDD or GND.
4 EN input Enable input where low level gives normal operation and it must be tied to VDD or GND; with EN=VDD the shutdown current is below 1 uA.
5 REXT input External resistor pin that sets the LED output current, with the datasheet listing 700 mA at 49 kΩ, 800 mA at 43 kΩ, 900 mA at 38 kΩ and 1400 mA at 24 kΩ.
6 GND power_in Ground pin, which should be connected to a large copper area on the PCB (and to the metal housing where possible) to aid heat dissipation.
7 GND power_in Ground pin, which should be connected to a large copper area on the PCB (and to the metal housing where possible) to aid heat dissipation.
8 LED output Negative terminal connection for the external LED, with an output withstand voltage limit of -0.3 V to 5.5 V.
