DX2213E

Dersem · LED Drivers · ESOP-8

DX2213E from Dersem, in a ESOP-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 VCC power_in Internal chip supply pin: the datasheet gives an absolute maximum of 8 V, a start-up voltage of 6.5 V, an undervoltage lockout threshold of 5.4 V, and states the chip starts operating once VCC exceeds 7 V.
2 EN input Mode-select input whose connection (floating, tied to GND, or via a resistor, suggested 75 kΩ to GND) sets the switching sequence of D1/D2, with a mode-select current of 30 µA and an absolute range of -0.3 to 6 V.
3 CS1 input Current-sense input for channel 1, where the external sense resistor sets the D1 output current against a 0.6 V reference (0.3 V when D1 and D2 are both on), with an absolute range of -0.3 to 6 V.
4 CS2 input Current-sense input for channel 2, where the external sense resistor sets the D2 output current against a 0.6 V reference (0.3 V when D1 and D2 are both on), with an absolute range of -0.3 to 6 V.
5 D2 output Constant-current output port for channel 2, rated for a high-voltage limit of 500 V and a maximum drain saturation current of 80 mA.
6 D1 output Constant-current output port for channel 1, rated for a high-voltage limit of 500 V and a maximum drain saturation current of 80 mA.
7 NC unconnected No internal connection; the datasheet specifies this pin as floating (悬空).
8 VIN power_in High-voltage supply input that feeds the chip through an internal high-voltage JFET (maximum JFET current 2.0 mA), with a rating of 500 V.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
