The PJ85718 is a digital temperature sensor with ±1°C accuracy. Temperature data can be read out directly via SMBus interface by MCU or SoC chip. PJ85718 has two independent channels: one remote and one local sensor. The remote sensor could be connected to an external Diode or BJT transistor (diode-connected mode).
Each chip is calibrated in factory before shipment to customers. There is no need for re-calibration anymore for ±1°C accuracy. It includes a band-gap circuit, an Analog to Digital converter, a calibration unit with nonvolatile memory and a digital interface block. It integrates an 11-bit ADC, which can offer 0.125°C resolution. The maximum temperature readout range can be up to 160oC plus offset shifting register. It has 2 logic output pin (/ALERT, /THERM) with open drain structure, which are active low as default. Available Package : MSOP-8P
