SE601-HF from Seaward Elec, 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 | DP | bidirectional | USB positive data line (D+). Used for fast charging protocol negotiation and voltage request signaling. Supports Apple 2.4A mode with 2.7V loading and QC voltage select reference at ~2V. |
| 2 | GND | power_in | Ground connection. Reference return for VDD and all internal circuitry. |
| 3 | FBO | output | Feedback output. Current source/sink output used to adjust the adapter's feedback network to control VBUS output voltage. Step size ~2 uA with RIREF=100 kΩ. |
| 4 | QC_EN | input | FCP/QC function enable input. High-impedance (Hi-Z) to enable FCP/QC fast charging protocols; LOW to disable and force DCP-only operation. |
| 5 | VDD | power_in | Chip power supply. Operating range 3.2 V to 5.5 V; typical supply current 200 uA at 5 V. Internal shunt clamp at ~4.75 V (IVDD=3.5 mA). UVLO turn-on 3.0 V typ, turn-off 2.9 V typ with 0.1 V hysteresis. |
| 6 | DM | bidirectional | USB negative data line (D-). Carries FCP signaling (TX/RX) and QC handshake. Internal ~19.53 kΩ pull-down and FCP RX/TX thresholds (VIH 1.5-3.6 V, VIL ≤1.0 V; VOH 2.35-3.6 V, VOL ≤0.3 V). |
