The PJ85775 is a digital temperature sensor with ±0.5°C accuracy. Temperature data can be read out directly via digital interface (compatible with SMBus, I2C or 2-wire) by MCU, Bluetooth Chip or SoC chip. PJ85775 supports I2C communication with speed up to 400 kHz. Each chip is specially calibrated for ±0.5°C (Max.) accuracy over 0°C to 50°C range in factory before shipment to customers. There is no need for re-calibration anymore for ±0.5°C accuracy. It includes a high precision band-gap circuit, a 12-bit analog to digital converter that can offer 0.0625°C resolution, a calibration unit with non volatile memory, and a digital interface block. It includes a band-gap circuit, an Analog to Digital converter, a calibration unit with non volatile memory and a digital interface block. It has ALERT logic output pin with open drain structure, which is selectable for active low or high by programming. ALERT response is compatible with SMBus ALERT Response Address (ARA). PJ85775 can be used as standalone thermostat. Available Package : SOP-8P and MSOP-8P.
