LM9061MX from Texas Instruments, in a SOIC-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 | Sense | input | The inverting input to the protection comparator, connected to the external MOSFET source pin and the load. |
| 2 | Threshold | input | The noninverting input to the protection comparator, and a current sink for the threshold resistor to set the allowed voltage drop across the external MOSFET. |
| 3 | Ground | power_in | Ground |
| 4 | Output | output | The gate drive connection. Charges, and discharges, the MOSFET gate. |
| 5 | VCC | power_in | The voltage supply pin. The VCC operating range has a minimum value of 7 V, and a maximum value of 26 V. |
| 6 | IREF | output | A resistor on this pin to ground sets the current through the threshold resistor, which sets the allowed voltage drop across the external MOSFET. |
| 7 | On/Off | input | The control pin. A low voltage, VIN(0), will disable device operation, while a high voltage, VIN(1), will enable device operation. |
| 8 | Delay | output | A capacitor on this pin to ground will provide a delay time between when the protection comparator detects excessive VGS across the MOSFET and when the gate drive circuitry is latched-OFF. |
