KP41141SGA

Kiwi Instruments · Power Distribution Switches · SOP-8

KP41141SGA 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 GND power_in IC reference ground, which is also the source of the internal power MOSFET.
2 GND power_in IC reference ground, which is also the source of the internal power MOSFET.
3 GND power_in IC reference ground, which is also the source of the internal power MOSFET.
4 VDD power_in IC supply pin; the datasheet gives a VDD DC supply rating of -0.3 to 9 V, a VDD clamp current of 5 mA, and typical VDD_ON and VDD_OFF thresholds of 3.1 V and 2.8 V.
5 Drain power_in Drain of the built-in power MOSFET; the Drain pin is rated -0.3 to 40 V and the internal MOSFET breakdown voltage is 40 V.
6 Drain power_in Drain of the built-in power MOSFET; the Drain pin is rated -0.3 to 40 V and the internal MOSFET breakdown voltage is 40 V.
7 Drain power_in Drain of the built-in power MOSFET; the Drain pin is rated -0.3 to 40 V and the internal MOSFET breakdown voltage is 40 V.
8 Drain power_in Drain of the built-in power MOSFET; the Drain pin is rated -0.3 to 40 V and the internal MOSFET breakdown voltage is 40 V.
