LM3880QMFX-1AB from Texas Instruments, 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 | Input supply pin, recommended 2.7 V to 5.5 V with an absolute maximum of 6 V, and should be placed as close as possible to the input supply (a 0.1 µF ceramic bypass is suggested where noise is present). |
| 2 | GND | power_in | Ground reference pin for the sequencer. |
| 3 | EN | input | Precision enable input with a 1.0 V to 1.4 V threshold (1.25 V typical) and a 7 µA internal pull-up; it must not be tied to VCC, and its recommended range is -0.3 V to VCC + 0.3 V with an absolute maximum of 6 V. |
| 4 | FLAG3 | output | Open-drain output flag 3, which must be pulled up to a supply (typically 100 kΩ), with a maximum of 6 V and a 50 mA maximum sink current, and a 0.4 V maximum low-level output at 1.2 mA. |
| 5 | FLAG2 | output | Open-drain output flag 2, which must be pulled up to a supply (typically 100 kΩ), with a maximum of 6 V and a 50 mA maximum sink current, and a 0.4 V maximum low-level output at 1.2 mA. |
| 6 | FLAG1 | output | Open-drain output flag 1, which must be pulled up to a supply (typically 100 kΩ), with a maximum of 6 V and a 50 mA maximum sink current, and a 0.4 V maximum low-level output at 1.2 mA. |
