JW7726CSOTB#TRPBF from JoulWatt Tech, in a SOT-23-6. 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 | VCC | power_in | Power supply input for the controller; bypass a capacitor between VCC and GND, and the recommended VCC range is 4V to 8.5V. |
| 2 | GND | power_in | Ground reference for the controller. |
| 3 | GT | output | Drives the external NMOSFET gate; the recommended GT range is 4V to 8.5V, with maximum pull-up current of 0.6 A and maximum pull-down current of 4 A. |
| 4 | VT | input | Sets the voltage-second product threshold through the resistance connected at this pin. |
| 5 | SW | input | Senses the external power MOSFET drain voltage and charges VCC; the recommended SW range is 4.7V to 120V, with an absolute maximum of -1 to 140V. |
| 6 | VO | input | Senses the output voltage and charges VCC; the recommended VO range is 4.7V to 25V, with an absolute maximum of -0.3 to 28V. |
