MST · LED Drivers · SOP-8
MST1174KP from MST, 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 | NC | unconnected | No connection; the datasheet lists this pin as not connected. |
| 2 | NC | unconnected | No connection; the datasheet lists this pin as not connected. |
| 3 | VIN | power_in | External power input from the positive battery terminal; DC supply range is 9V to 18V, and VIN to VOUT must not exceed 45V (absolute maximum). |
| 4 | VIN | power_in | External power input from the positive battery terminal; DC supply range is 9V to 18V, and VIN to VOUT must not exceed 45V (absolute maximum). |
| 5 | VOUT | power_out | Flasher output that switches the bulb (connected between VOUT and GND) on and off at about 1.42Hz with 50% duty; current is limited to 12A and the peak output current is internally limited. |
| 6 | VOUT | power_out | Flasher output that switches the bulb (connected between VOUT and GND) on and off at about 1.42Hz with 50% duty; current is limited to 12A and the peak output current is internally limited. |
| 7 | CEXT | passive | Connects the external energy-storage capacitor (application note cites 47uF 25V) that powers the internal supply, which reaches about 5.3V; CEXT to VOUT must not exceed 5.3V (absolute maximum). |
| 8 | NC | unconnected | No connection; the datasheet lists this pin as not connected. |
