Texas Instruments · Supervisor And Reset ICs · SOT-23-5
TLV840NADL20DBVR 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 | Open-drain active-low reset output asserted when VDD falls below the 2.0 V negative voltage threshold (VIT-) and held low for reset delay period (tD) after VDD recovery above threshold plus 5% hysteresis. |
| 2 | VDD | power_in | Input supply voltage monitor; TLV840 operates with recommended voltage range 0.7 V to 6 V. |
| 3 | GND | power_in | Ground; negative supply rail. |
| 4 | NC | unconnected | No Connect; pin can be left floating or connected to ground. |
| 5 | NC | unconnected | No Connect; pin can be left floating or connected to ground. |
