LM3880QMFE-1AF 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; the datasheet specifies VCC to GND of 2.7 V to 5.5 V and recommends placing the supply connection as close as possible to the device, with a 0.1 µF ceramic bypass capacitor 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; the datasheet recommends not tying EN directly to VCC and keeping it below threshold until VCC reaches its minimum operating voltage. |
| 4 | FLAG3 | output | Open-drain output flag 3, released last in the power-up sequence and asserted first in power-down; it must be pulled up, typically with 100 kΩ, and FLAG pins are limited to -0.3 V to 6 V with 50 mA maximum output current. |
| 5 | FLAG2 | output | Open-drain output flag 2, sequenced between FLAG1 and FLAG3; it must be pulled up, typically with 100 kΩ, and FLAG pins are limited to -0.3 V to 6 V with 50 mA maximum output current. |
| 6 | FLAG1 | output | Open-drain output flag 1, released first in the power-up sequence; it must be pulled up, typically with 100 kΩ, and FLAG pins are limited to -0.3 V to 6 V with 50 mA maximum output current. |
