TPS3801K33DCKR

Texas Instruments · Supervisor And Reset ICs · SC-70-5

TPS3801K33DCKR from Texas Instruments, in a SC-70-5. 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 Ground reference. Tied internally to pin 2.
2 GND power_in Ground reference. Tied internally to pin 1.
3 RESET output Active-low push-pull reset output. Asserts low whenever VDD is below the 2.93 V threshold or MR is held low, and remains asserted for the ~200 ms recovery delay after VDD returns above threshold. IOL = 5 mA, IOH = -5 mA max.
4 VDD power_in Supply and monitored voltage input. Operating range 2 V to 6 V for the K33 option; also feeds the internal comparator monitoring the 2.93 V threshold. A 0.1 µF bypass capacitor is recommended near this pin.
5 MR input Active-low manual reset input with an internal ~30 kΩ pull-up to VDD. Pulling MR low forces RESET low; leaving it floating or tied high enables normal supervisor operation. VIL = 0.3 x VDD, VIH = 0.7 x VDD.
