TPS3809I50MDBVREP

Texas Instruments · Supervisor And Reset ICs · SOT-23-3

TPS3809I50MDBVREP from Texas Instruments, in a SOT-23-3. 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 GND power_in Ground reference for the supervisor; all voltages are specified with respect to GND.
2 RESET output Active-low reset output that is asserted when VDD is above 1.1 V but below VIT, and returns high after a delay td of 200 ms typical once VDD rises above VIT.
3 VDD power_in Supply voltage input that is monitored against the 4.55 V threshold; recommended operating range is 2 V to 6 V, with a 0.1 µF ceramic bypass capacitor placed near it.
