TPS3103H20DBVR

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

TPS3103H20DBVR 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 RESET output Low-level active reset output with push-pull or open-drain output stage.
2 GND power_in Ground reference.
3 MR input Manual reset input; pulling low forces RESET output low, which remains low for a timeout period after MR returns high; connect to VDD or leave unconnected when not used.
4 PFI input Power fault input compared to internal 0.551V reference with no additional delay; connect to VDD when not used.
5 PFO output Power fault output which goes high when PFI voltage exceeds 0.551V.
6 VDD power_in Supply voltage; powers the device and is monitored to generate RESET output.
