TPS3840DL25DBVRQ1

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

TPS3840DL25DBVRQ1 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 RESET tri_state Active-low open-drain reset output asserted when MR is pulled low or VDD falls below voltage threshold VIT-.
2 VDD power_in Input power supply voltage for device operation, recommended range 1.5V to 10V.
3 GND power_in Ground reference.
4 MR input Manual reset input, pull low to logic level VMR_L to assert reset output, can be left floating when not in use.
5 CT passive Capacitor timing pin, connect external capacitor to program reset delay time tD or leave floating for fixed minimum delay.
