SE2513-HF from Seaward Elec, 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 | DP1 | bidirectional | Channel 1 USB D+ data-line port; the absolute maximum voltage from DP1 to GND is -0.3 V to 7 V, and it is driven to the divider or 1.2 V charging levels selected by SEL. |
| 2 | GND | power_in | Reference ground for the device. |
| 3 | DP2 | bidirectional | Channel 2 USB D+ data-line port; the absolute maximum voltage from DP2 to GND is -0.3 V to 7 V, and it is driven to the divider or 1.2 V charging levels selected by SEL. |
| 4 | DM2 | bidirectional | Channel 2 USB D- data-line port; the absolute maximum voltage from DM2 to GND is -0.3 V to 7 V, and it is driven to the divider or 1.2 V charging levels selected by SEL. |
| 5 | IN | power_in | Power input for the device, specified for 4.5 V to 5.5 V operation with an absolute maximum of -0.3 V to 7 V to GND and an undervoltage lockout of about 4.1 V (typical). |
| 6 | DM1 | bidirectional | Channel 1 USB D- data-line port; the absolute maximum voltage from DM1 to GND is -0.3 V to 7 V, and it is driven to the divider or 1.2 V charging levels selected by SEL. |
