DX7002

Dersem · LED Drivers · SOP-8

DX7002 from Dersem, 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 LD input Analog/step dimming input: 0.2-1.2 V sets analog dimming, LD floating selects full brightness, LD pulled above VDD by 1 V selects half-current mode, and the absolute maximum rating is -0.3 to 7.0 V.
2 PWM input PWM dimming input that enables output when high (rising threshold 1.4 V, falling 0.8 V), responds to pulses down to 60 ns, defaults high when floating, and is rated -0.3 to 7.0 V.
3 VDD power_in Chip supply pin that starts up above 4.2 V, clamps at about 5.0-5.2 V, needs a bypass capacitor of at least 1.0 µF placed close to the pin, and is rated -0.3 to 7.0 V.
4 CS input Source of the internal power MOSFET and current-sense input, where the sense resistor sets the output current (Iout = 0.2 V / RCS) and the overcurrent threshold is 216-264 mV; rated -0.3 to 7.0 V.
5 D passive Drain of the internal 80 mΩ / 60 V power MOSFET; this is a heat-sink pin that must be thermally managed according to the datasheet.
6 D passive Drain of the internal 80 mΩ / 60 V power MOSFET; this is a heat-sink pin that must be thermally managed according to the datasheet.
7 GND power_in Chip ground for the controller and gate driver.
8 GND power_in Chip ground for the controller and gate driver.
