Texas Instruments · Supervisor And Reset ICs · SOT-23-5
TPS3840DL16DBVR 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; asserts low when MR is driven below 600mV or VDD drops below VIT- (1.6V); deasserts high after programmable delay tD when VDD rises above VIT+ (1.7V) and MR is high (≥0.7·VDD) or floating. |
| 2 | VDD | power_in | Positive power supply input (1.5V to 10V operating range); monitored by internal comparator for voltage threshold detection. |
| 3 | GND | power_in | Ground; common return path for power supply and signal references. |
| 4 | MR | input | Manual reset input; drive low (≤600mV) to assert reset output, or leave high (≥0.7·VDD) or floating for normal operation; includes 100kΩ internal pull-up resistor to VDD. |
| 5 | CT | passive | Capacitor connection terminal for user-programmable reset delay time tD; connect external capacitor (max 10µF) to adjust delay from 50µs minimum (no capacitor) to 6.2s maximum (10µF); leave floating for 50µs minimum fixed delay. |
