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. |
