Technical details

Analog temperature sensor with a 10 mV/°C output — no digital bus, no configuration

It is a local sensor — it measures its own die temperature — and delivers an analog voltage output that a microcontroller ADC or a comparator can read directly. No digital interface, no I²C or SPI configuration; just power it from 4V to 10V and read the voltage. Typical applications include thermal shutdown monitoring, fan control, battery temperature supervision, and general-purpose system temperature monitoring in motor drives, power supplies, and outdoor telecom equipment.

ROHS3 compliant.
