TMP112AQDRLRQ1

Texas Instruments · Temperature Sensors · SOT-563

TMP112AQDRLRQ1 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 SCL input Serial clock input for the I2C/SMBus/two-wire bus; the device never drives SCL, and it needs an external pull-up resistor (5 kΩ recommended, no more than 3 mA on the pin).
2 GND power_in Ground reference for the device.
3 ALERT output Open-drain over-temperature alert output that requires a pull-up resistor and should be connected to GND if unused.
4 ADD0 input Address select input that must be connected to GND, V+, SDA or SCL to set one of four I2C target addresses.
5 V+ power_in Power supply input, 1.4 V to 3.6 V for the TMP112-Q1 (the TMP112AQDRLRQ1 orderable).
6 SDA bidirectional Serial data line, open-drain I/O that requires a pull-up resistor.
