KP107LSPA from Kiwi Instruments, 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 | HVDD | power_in | High-voltage supply pin for the chip; the datasheet gives an absolute maximum of -0.3 to 650 V, a start-up threshold HVDD_ON of 10 to 13 V (11.5 V typical), and a shut-off threshold HVDD_OFF of 5.8 to 7.5 V (6.6 V typical). |
| 2 | NC | unconnected | Non-functional pin that must be left floating (unconnected) in the application. |
| 3 | GATE | output | Gate drive output that connects to the gate of an external power MOSFET; the datasheet gives no voltage or current limit for this pin. |
| 4 | CS | input | Current-sense input for peak-current limiting, with a reference Vcs(max) of 590 to 610 mV (600 mV typical) and an absolute maximum voltage of -0.3 to 7 V. |
| 5 | GND | power_in | Chip reference ground, bonded together with pins 6, 7 and 8. |
| 6 | GND | power_in | Chip reference ground, bonded together with pins 5, 7 and 8. |
| 7 | GND | power_in | Chip reference ground, bonded together with pins 5, 6 and 8. |
| 8 | GND | power_in | Chip reference ground, bonded together with pins 5, 6 and 7. |
