LM3880MFX-1AF

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

LM3880MFX-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 recommended supply range is 2.7 V to 5.5 V and the absolute maximum is 6 V, with a 0.1 µF ceramic bypass suggested where noise is present.
2 GND power_in Ground reference pin for the sequencer.
3 EN input Precision enable input with a 1.25 V (typical) threshold, a 7 µA internal pull-up, and an absolute range of -0.3 V to VCC + 0.3 V; the datasheet recommends not tying it directly to VCC.
4 FLAG3 output Open-drain output 3, which must be pulled up to a supply no higher than VCC + 0.3 V; it sinks at most 50 mA and has a low-level output of 0.4 V max at 1.2 mA.
5 FLAG2 output Open-drain output 2, which must be pulled up to a supply no higher than VCC + 0.3 V; it sinks at most 50 mA and has a low-level output of 0.4 V max at 1.2 mA.
6 FLAG1 output Open-drain output 1, which must be pulled up to a supply no higher than VCC + 0.3 V; it sinks at most 50 mA and has a low-level output of 0.4 V max at 1.2 mA.
