LM3880MF-1AB from Texas Instruments, 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 | VCC | power_in | Input supply. Operating range 2.7 V to 5.5 V; absolute maximum 6 V. Powers the internal sequencer logic and reference. |
| 2 | GND | power_in | Ground reference for the device (0 V). Connect to the system ground plane. |
| 3 | EN | input | Precision enable input. Rising edge above VEN (typ. 1.25 V, range 1.0-1.4 V) initiates the power-up sequence; a falling edge below the threshold triggers the reverse power-down sequence. Input current ~7 μA at VEN = 0 V. Absolute maximum -0.3 V to 6 V. |
| 4 | FLAG3 | output | Open-drain enable output 3 (third to assert on power-up, first to de-assert on power-down). Requires external pull-up; may be pulled to a rail higher than VCC (up to 6 V absolute max) to interface with higher-voltage enable pins. Sink capability up to 1.2 mA at VOL ≤ 0.4 V; leakage ~1 nA (max 20 nA) when off. |
| 5 | FLAG2 | output | Open-drain enable output 2 (second to assert on power-up, second to de-assert on power-down). Requires external pull-up; may be pulled to a rail higher than VCC (up to 6 V absolute max). Sink capability up to 1.2 mA at VOL ≤ 0.4 V; leakage ~1 nA (max 20 nA) when off. |
| 6 | FLAG1 | output | Open-drain enable output 1 (first to assert on power-up, last to de-assert on power-down). Requires external pull-up; may be pulled to a rail higher than VCC (up to 6 V absolute max). Sink capability up to 1.2 mA at VOL ≤ 0.4 V; leakage ~1 nA (max 20 nA) when off. |
