TMP303DDRLR

Texas Instruments · Thermostat Switches · SOT-563

TMP303DDRLR 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 HYSTSET0 input Digital input pin used to set thermal hysteresis; configure with HYSTSET1 to set 1°C, 2°C, 5°C, or 10°C hysteresis window.
2 GND power_in Ground reference.
3 OUT output Active high push-pull digital output pin that goes high when measured temperature exceeds trip point; does not require pullup resistor; output voltage VOH minimum (VS - 0.4) V at IOH = 0.5 mA.
4 SOH input Set output high input pin with 100 kΩ internal pulldown resistor; when pulled high forces OUT pin high regardless of temperature.
5 VS power_in Power supply positive voltage; operating range 1.4 V to 3.6 V.
6 HYSTSET1 input Digital input pin used to set thermal hysteresis; configure with HYSTSET0 to set 1°C, 2°C, 5°C, or 10°C hysteresis window.
