Active production — no end-of-life watch needed
The LM95221CIMMX/NOPB: ROHS3 compliant, so it ships into RoHS-regulated markets without exemption paperwork.
Local/remote sensing with SMBus interface
This is a digital temperature sensor that monitors both its own die temperature (local) and an external diode-connected transistor (remote), outputting readings over an SMBus serial interface. Local resolution is 9 bits; the remote channel resolves to 10 bits, which yields a finer temperature step for the external sense point. Accuracy is specified at ±3°C across the 0°C to 85°C test range — adequate for thermal management and over-temperature protection in computing, telecom, and industrial equipment.
Supply and temperature envelope
The 8-VSSOP footprint (3.00 mm × 3.00 mm body, 0.65 mm pitch) fits tight PCB layouts; the 8-TSSOP and 8-MSOP package options share the same pad layout.
