KP4214ESGA from Kiwi Instruments, 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 | HVDD | power_in | Chip supply pin with start-up voltage VDDON of 13.5-17 V (16 V typ), undervoltage-protection threshold VDDOFF of 8.5-10.5 V (9.5 V typ), and a 650 V VDD breakdown rating. |
| 2 | NC | unconnected | Non-functional pin; leave floating in use. |
| 3 | Gate | output | High-voltage MOSFET gate drive output pin. |
| 4 | CS | input | Current-sense input with current limit VCS_MAX of 190-200 mV (195 mV typ), open-circuit detection threshold VCS_MIN_L of 5-15 mV, and absolute voltage range of -0.3 to 8 V. |
| 5 | DET | input | MOSFET drain-voltage detection input with clamp voltage VDETClamp of 2 V, LED short-circuit threshold IDETL of 36-44 uA, and absolute voltage range of -0.3 to 8 V. |
| 6 | GND | power_in | Chip reference ground. |
| 7 | COMP | input | Ripple-cancellation loop compensation pin; when left floating the compensation uses an internal 3 uF capacitor, the COMP clamp voltage is 1.8-2.2 V, and absolute voltage range is -0.3 to 8 V. |
| 8 | Drain | passive | Internal power MOSFET drain input; for the KP4214ESGA the Drain absolute voltage range is -0.3 to 80 V and the MOSFET breakdown voltage VBR is 80 V. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
