LM3880QMFX-1AE

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

LM3880QMFX-1AE 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 pin, 2.7 V to 5.5 V operating range (absolute max 6 V). A 0.1 µF ceramic bypass capacitor is recommended when noise is present on VCC.
2 GND power_in Device ground reference.
3 EN input Precision enable input referenced to an internal 1.25 V bandgap (VEN threshold 1.0 V min / 1.4 V max). Sourcing 7 µA internal pull-up current; asserting EN starts the power-up sequence, de-asserting starts the power-down sequence. Should not be tied directly to VCC.
4 FLAG3 output Open-drain sequencer output 3, requires external pull-up (typ. 100 kΩ) to VCC or a separate flag supply not exceeding VCC + 0.3 V. VOL = 0.4 V max at IFLAG = 1.2 mA; max sink current 50 mA; leakage 20 nA max at 3.3 V.
5 FLAG2 output Open-drain sequencer output 2, requires external pull-up (typ. 100 kΩ) to VCC or a separate flag supply not exceeding VCC + 0.3 V. VOL = 0.4 V max at IFLAG = 1.2 mA; max sink current 50 mA; leakage 20 nA max at 3.3 V.
6 FLAG1 output Open-drain sequencer output 1, requires external pull-up (typ. 100 kΩ) to VCC or a separate flag supply not exceeding VCC + 0.3 V. VOL = 0.4 V max at IFLAG = 1.2 mA; max sink current 50 mA; leakage 20 nA max at 3.3 V.
