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).
