DX7001 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/segmented dimming input: floating selects full brightness, a pull-up above 20 µA (or a level 1 V above VDD) selects half-current mode, 0.2-1.2 V selects analog dimming with output off below 0.2 V, and absolute maximum is −0.3 to 7.0 V. |
| 2 | PWM | input | PWM dimming input: output is enabled when high and disabled when low, with rising threshold 1.4 V and falling threshold 0.8 V, resolving pulses down to 60 ns, defaulting high when floating, and absolute maximum of −0.3 to 7.0 V. |
| 3 | VDD | power_in | Chip supply pin, clamped to about 5.0 V (typical), which requires a bypass capacitor of at least 1.0 µF placed close to the pin; absolute maximum is −0.3 to 7.0 V. |
| 4 | CS | input | Source of the internal power MOSFET and current-sense input, where the 0.2 V reference sets output current as Iout = 0.2 V / RCS and the overcurrent threshold is 216-264 mV at VDD = 5 V. |
| 5 | D | output | Drain of the internal 200 mΩ / 100 V power MOSFET; this is a heat-dissipation pin that must be thermally treated according to the datasheet note. |
| 6 | D | output | Drain of the internal 200 mΩ / 100 V power MOSFET; this is a heat-dissipation pin that must be thermally treated according to the datasheet note. |
| 7 | GND | power_in | Chip ground, which per the layout guidance should be single-point connected with the VDD capacitor ground and the CS sense resistor ground. |
| 8 | GND | power_in | Chip ground, which per the layout guidance should be single-point connected with the VDD capacitor ground and the CS sense resistor ground. |
