TPS3840DL46DBVRQ1

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

TPS3840DL46DBVRQ1 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 output Active-low open-drain output driven low when MR pin is pulled to logic low or VDD falls below negative voltage threshold VIT-, remaining asserted for programmed delay time tD.
2 VDD power_in Supply voltage input monitored by TPS3840-Q1 with operating range 1.5V to 10V.
3 GND power_in Ground reference.
4 MR input Manual reset input pin; pull to logic low (VMR_L) to assert reset output, can be left floating when not in use.
5 CT passive Capacitor time delay pin for programmable reset delay; connect external capacitor to adjust delay from 50µs (no capacitor) to 6.2s (10µF).
