JW7111SSOTB#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 | VIN | power_in | Input, connect a 10μF or greater ceramic capacitor from VIN to GND as close to the IC as possible; VIN operating range is 2.7V to 5.5V. |
| 2 | GND | power_in | Ground (0V). |
| 3 | EN | input | Enable input; on this active-high JW7111S variant, logic high turns on the power switch, with EN high-level input 1.4V minimum and EN voltage range 0V to 5.5V. |
| 4 | FLG | output | Active-low open-drain output, asserted during over-current and over-temperature; FAULT output low voltage is 180mV max at 1mA with a 7.5ms deglitch time. |
| 5 | ILIM | passive | Use an external resistor to set the current-limit threshold; recommended 10kΩ≦RLIM≦49.9kΩ. |
| 6 | VOUT | power_out | Output voltage; VOUT pin voltage is rated 0V to (VIN+0.2V) under recommended operating conditions. |
