LM74701QDDFRQ1 from Texas Instruments, in a TSOT-23-8. 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 | GATE | output | Gate drive output with 11 mA typical source and 2000 mA peak sink current; voltage range -0.3 V to 15 V relative to ANODE. |
| 2 | ANODE | power_in | Input power pin with 3.2 V to 65 V input range, 3.9 V power-on reset rising threshold, and -33 V reverse voltage rating. |
| 3 | VCAP | output | Charge pump output up to 600 µA sourcing current to charge external 0.1 µF minimum capacitor for gate drive. |
| 4 | SW | output | Battery voltage sensing output internally switched to ANODE when EN is high for external resistor divider monitoring. |
| 5 | GND | power_in | Ground reference pin. |
| 6 | EN | input | Enable input pin with input low threshold 0.5 V to 1.22 V and high threshold 1.06 V to 2.6 V; accepts voltage range -33 V to 65 V. |
| 7 | N.C | unconnected | No connect pin; keep floating. |
| 8 | CATHODE | power_out | Output power pin connected to external N-channel MOSFET drain; voltage range is -5 V to VCLAMP (43 V maximum) relative to ANODE. |
