TPS3838K33QDBVRQ1

Texas Instruments · Supervisor And Reset ICs · SOT-23-5

TPS3838K33QDBVRQ1 from Texas Instruments, in a SOT-23-5. 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 CT input Timing capacitor input; connect to GND for 10 ms power-on reset delay or to VDD for 200 ms delay.
2 GND power_in Ground; negative power supply reference.
3 MR input Manual reset input (active-low); internal 30 kΩ pull-up resistor to VDD; pull low to assert RESET output.
4 VDD power_in Positive supply voltage input, operating range 1.6 V to 6 V per recommended operating conditions.
5 RESET tri_state Active-low open-drain reset output; asserted (low) when VDD drops below threshold voltage VIT or when MR is pulled low.
