JW7726BLSOTB#TR 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 | VO | input | Output voltage sensing pin that charges VCC when VO is above 4.6V (rising) and stops charging below 4.5V (falling); recommended operating range is 4.7V to 27V, absolute maximum -0.3V to 30V. |
| 2 | GND | power_in | Ground reference for the controller; the VCC bypass capacitor is connected between VCC and this pin. |
| 3 | VT | passive | Sets the volt-second threshold used to reject parasitic ringing on SW; the threshold is programmed by the resistance connected to this pin (Figure 3 relates volt-second value to VT resistance, 25K to 250K). |
| 4 | VCC | power_in | Controller supply pin that requires a bypass capacitor to GND; recommended operating range is 4V to 8V, absolute maximum -0.3V to 10V. |
| 5 | GT | output | Gate drive output for the external NMOSFET; the datasheet gives a maximum gate pull-up current of 0.65A and pull-down current of 4.7A, with absolute maximum -0.3V to 10V. |
| 6 | SW | input | External MOSFET drain voltage sensing pin used to detect turn-on (VSW below -150mV) and turn-off (VSW above -10mV); recommended operating range is 4.7V to 130V, absolute maximum -1V to 150V. |
