PJ85775 Digital Temperature Sensor

PANJIT’s PJ85775 is a digital temperature sensor with ±0.5°C accuracy. Temperature data can be read directly via digital interface (compatible with SMBus, I²C, or 2-wire) by MCU, Bluetooth chip, or SoC. PJ85775 supports I²C communication with speeds of up to 400 kHz. Each chip is specially calibrated for ±0.5°C (max.) accuracy over a 0°C to +50°C range in the factory before shipment to customers. There is no need for recalibration 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 has an ALERT logic output pin with an open drain structure, selectable for active low or high by programming. ALERT response is compatible with SMBus ALERT Response Address (ARA). PJ85775 can be used as a standalone thermostat. It is available in SOP-8 and MSOP-8 packages.
