TPS3840DL31DBVRQ1

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

TPS3840DL31DBVRQ1 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 output reset signal; driven low when MR pin is driven low or VDD falls below VIT-; remains low for delay time tD after MR returns high and VDD rises above VIT+; absolute maximum -0.3 to 12V.
2 VDD power_in Supply voltage input pin; device operates within recommended range 1.5V to 10V; absolute maximum -0.3 to 12V.
3 GND power_in Ground reference pin.
4 MR input Manual reset input pin; assert reset by pulling to logic low; recommended voltage 0 to VDD V; absolute maximum -0.3 to 12V.
5 CT passive Time delay capacitor pin; external capacitor adjusts reset delay from 50µs (no capacitor) to 6.2s (10µF); absolute maximum -0.3 to 5.5V.
