The MAX31827 is a ±1°C accuracy from -40°C to +125°C (12 bits) local temperature switch and sensor with I2C/SMBus interface. The combination of small 6-bump wafer-level package (WLP) and high accuracy makes this temperature sensor/switch ideal for a wide range of applications. It can be used as a temperature switch with preconfigured thresholds and/or as a temperature sensor with I2C interface. When the part operates as an independent temperature switch, the I2C interface doesn't have to be used. This enables use of the part in systems that require thermal protection implemented in hardware, without the need for reconfiguration or use of software/firmware during normal operation.


One-time programmable (OTP) ALARM functionality enables use of the part as a safety mechanism in systems where power dissipation is a challenge.

The I2C/SMBus-compatible serial interface accepts standard write and read commands to read the temperature data and configure the behavior of the sensor. Bus timeout resets the interface if the clock is low for more than 30ms (nominal). Packet error checking (PEC) helps prevent communication errors when used with a master that supports this feature.

The MAX31827 is available in a 6-bump WLP and operates over the -45°C to +145°C temperature range.
