LM3880QMFX-1AC

Texas Instruments · Supervisor And Reset ICs · SOT-23-6

LM3880QMFX-1AC 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 for the sequencer, specified at 2.7 V to 5.5 V relative to GND with a 6 V absolute maximum, and should be placed as close as practical to the input supply.
2 GND power_in Ground reference pin for the device.
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 at VEN = 0 V; the recommended voltage range is -0.3 V to VCC + 0.3 V, and the datasheet advises not to connect EN directly to VCC.
4 FLAG3 output Open-drain output 3 that must be pulled up externally (100 kΩ typical), with a 50 mA maximum on-state output current, 0.4 V maximum low-level output at 1.2 mA, and a pull-up supply not exceeding VCC + 0.3 V.
5 FLAG2 output Open-drain output 2 that must be pulled up externally (100 kΩ typical), with a 50 mA maximum on-state output current, 0.4 V maximum low-level output at 1.2 mA, and a pull-up supply not exceeding VCC + 0.3 V.
6 FLAG1 output Open-drain output 1 that must be pulled up externally (100 kΩ typical), with a 50 mA maximum on-state output current, 0.4 V maximum low-level output at 1.2 mA, and a pull-up supply not exceeding VCC + 0.3 V.
