TPS3809K33DBVR

Texas Instruments · Supervisor and Reset ICs · SOT-23

TPS3809K33DBVR from Texas Instruments, in a SOT-23. 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 GND power_in Device ground reference. All voltages are referenced to this pin.
2 RESET output Active-low, open/push-pull reset output. Driven low while VDD is below the threshold VIT (2.93 V for K33) and for td = 200 ms (typ) after VDD rises above VIT. VOL ≤ 0.4 V at IOL = 2 mA (VDD = 3.3 V); output is undefined for VDD < 1.1 V. Overlined RESET in the datasheet indicates active-low polarity.
3 VDD power_in Supply voltage input, also the monitored voltage. Recommended operating range 2 V to 6 V; absolute max 7 V. Bypass with a 0.1 μF ceramic capacitor to GND close to the pin for threshold stability.
