Low Power Temperature Sensor Small WLP Package MAX31875

MAX31875 is a very small WLP package low power temperature sensor. MAX31875 supports high, low triggers stored in EEPROM for hystersis or limit alarms using comparator or interrupt mode. One-shot/shutdown or continuous modes are available.

Notes

The MAX31875 is a extremely small WLP package temperature sensor. It supports high, low alarm triggers or hysteresis levels stored in NVRAM. The MAX31875 can operate in shutdown and one-shot mode for very low power applications.

While in standby mode, the current consumed is typically 500nA. Average current is typically <10uA. During a temperature conversion, the typical supply current increases to 80μA. The time of the conversion is dependent on the conversion resolution selected in the configuration register. A 9-bit conversion takes about 18 msec and a 12 bit conversion will be about 140 msec.

Key Features
