# TMP708AQDBVRQ1

**Texas Instruments** · Temperature Sensors · SOT-23-5

TMP708AQDBVRQ1 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 | SET | input | Temperature set-point input; an external 1% resistor is connected between SET and GND, and the input voltage range is 0 V to VCC. |
| 2 | GND | power_in | Device ground, which the external set-point resistor and the VCC bypass capacitor return to. |
| 3 | OT | output | Open-drain, active-low overtemperature output that requires an external pullup to VCC (greater than 10 kΩ recommended), with a 6 V absolute maximum rating and 20 mA absolute maximum output current. |
| 4 | HYST | input | Digital hysteresis select: tie to VCC for 10°C hysteresis or to GND for 30°C hysteresis, since other voltages can cause abnormal supply current or malfunction. |
| 5 | VCC | power_in | Power-supply input rated 2.7 V to 5.5 V, to be bypassed with a 0.1 µF capacitor placed as close as possible to the pin. |
