TPS3840DL20DBVR

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

TPS3840DL20DBVR 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 Low-level active reset output signal; pulled to logic low when MR pin is driven low or VDD drops below VIT-, remains low for reset delay time (tD) after recovery before releasing to logic high.
2 VDD power_in Input supply voltage from 1.5V to 10V; monitored by internal comparator to determine reset state.
3 GND power_in Ground connection.
4 MR input Manual reset input; pull to logic low to assert reset; apply logic high or leave floating for normal operation with internal pull-up resistor RMR = 100 kΩ.
5 CT passive Capacitor delay time pin; connect external capacitor (≤10µF) to program reset delay time; leave floating for minimum 50µs fixed delay.
