LM74700QDDFRQ1 from Texas Instruments, in a TSOT-23-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | EN | input | Enable input pin functioning when voltage exceeds input high threshold of 1.06V. |
| 2 | GND | power_in | Ground reference pin providing reference potential for device operation. |
| 3 | N.C | unconnected | No connection, internally unconnected. |
| 4 | VCAP | output | Charge pump output sourcing typical 300µA charging current to external capacitor. |
| 5 | ANODE | power_in | Anode and input power supply accepting 3.2V to 65V operating range, withstands -65V reverse voltage. |
| 6 | GATE | output | Gate drive output sourcing 11mA peak and sinking 2370mA peak to control external N-channel MOSFET gate. |
| 7 | N.C | unconnected | No connection, internally unconnected. |
| 8 | CATHODE | input | Cathode of diode and MOSFET drain connection, detects reverse current when voltage falls below -11mV relative to ANODE. |
