# TMP302CQDRLRQ1

**Texas Instruments** · Temperature Sensors · SOT-563

TMP302CQDRLRQ1 from Texas Instruments, in a SOT-563. 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 | TRIPSET0 | input | Digital input used in combination with TRIPSET1 to select the trip threshold temperature. |
| 2 | GND | power_in | Ground return. |
| 3 | OUT | output | Open-drain, active-low digital output that signals when temperature threshold is exceeded. |
| 4 | HYSTSET | input | Digital input used to set the amount of thermal hysteresis (5°C or 10°C). |
| 5 | VS | power_in | Power supply input, operating range 1.4 V to 3.6 V. |
| 6 | TRIPSET1 | input | Digital input used in combination with TRIPSET0 to select the trip threshold temperature. |
