TPS3840DL35DBVR 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 | Open-drain active-low output reset signal; asserts low when VDD < VIT- or MR pulled below 600mV, remains low for programmable delay tD, then releases high after VDD exceeds VIT+ and MR exceeds 0.7·VDD. |
| 2 | VDD | power_in | Input power supply voltage monitored by internal comparator; operating range 1.5V to 10V; supplies device logic and reference circuitry. |
| 3 | GND | power_in | Ground reference and return path for device and all external circuits. |
| 4 | MR | input | Manual reset active-low input; pulling below 600mV (VMR_L) asserts reset regardless of VDD state; leave floating or pull above 0.7·VDD (VMR_H) for normal operation; internal 100kΩ pull-up resistor provided. |
| 5 | CT | passive | Capacitor timing pin for user-programmable reset delay; connect external capacitor (max 10µF) to GND to program delay from 50µs minimum (floating) to 6.2s (10µF); internal resistance RCT 350-650kΩ. |
