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. |
