TPS3840PL30DBVRQ1

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

TPS3840PL30DBVRQ1 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 is pulled to logic low or VDD falls below VIT-, remains low for programmable delay tD after MR is released and VDD rises above VIT+.
2 VDD power_in Input Supply Voltage with recommended operating range 1.5V to 10V monitored by internal comparator against fixed threshold voltage VIT-.
3 GND power_in Ground reference.
4 MR input Manual Reset input pin pulled low to assert reset signal, internally pulled high to VDD with 100kΩ pull-up resistance, can be left floating when not used.
5 CT passive Capacitor Time Delay pin for external capacitor connection to adjust programmable reset delay from 50µs (floating) to 6.2s (10µF capacitor).
