LM74700QDBVTQ1 from Texas Instruments, in a SOT-23-6. 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 | VCAP | power_out | Charge pump output regulated between 10.8-13.9 V with 162-600 µA source capability; connect 0.1 µF minimum external capacitor. |
| 2 | GND | power_in | Ground reference pin. |
| 3 | EN | input | Enable input with low threshold 0.5-0.9 V and high threshold 1.06-2.6 V; can be connected to ANODE for always-ON operation. |
| 4 | CATHODE | input | MOSFET drain sense input; enables reverse current blocking when voltage falls below -11 mV relative to ANODE. |
| 5 | GATE | output | Gate drive output with 3-11 mA source and 2370 mA peak sink current; regulates ANODE-CATHODE voltage to 20 mV during forward conduction. |
| 6 | ANODE | power_in | Power supply input operating from 3.2-65 V with -65 V reverse voltage withstand; connects to external MOSFET source and protected circuit anode. |
