Dersem · LED Drivers · SOP-8
DX7601 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 | VDD | power_in | Chip supply pin with absolute maximum -0.3 to 7.0 V, an internal clamp of about 5.2 to 5.4 V, a rising UVLO threshold of 3.4 V with 0.2 V hysteresis, and a bypass capacitor of at least 1.0 µF placed next to the pin. |
| 2 | MODE | input | Brightness select pin: floating or grounded gives full brightness, a high level gives half brightness, with an absolute maximum of -0.3 to 7.0 V and an internal pull-down resistor of 40 kΩ. |
| 3 | NC | unconnected | Floating pin with no internal connection, as listed in the datasheet pin description. |
| 4 | CS | input | Source terminal of the internal power MOSFET and current-sense input, with an absolute maximum of -0.3 to 7.0 V and an over-current threshold of 400 mV; output current is set by Iout = 0.17 V / Rcs. |
| 5 | D | output | Drain terminal of the internal power MOSFET, which is a heat-dissipation pin and must be thermally managed. |
| 6 | D | output | Drain terminal of the internal power MOSFET, which is a heat-dissipation pin and must be thermally managed. |
| 7 | GND | power_in | Chip ground; the VDD capacitor ground should be tied to the CS sense resistor ground at a single point, per the PCB layout guidance. |
| 8 | GND | power_in | Chip ground; the VDD capacitor ground should be tied to the CS sense resistor ground at a single point, per the PCB layout guidance. |
