The new sensor is smaller than previous-generation sensors, measuring 2x2mm, and has an ultra-low 50-microA operating current, a power-saving 3-microA standby current, and a one-shot mode that makes the device suitable for battery-powered devices.

One-shot operation allows the sensor to sleep for extended periods, waking only to provide an instantaneous reading when triggered by the system. The STTS751 is accurate to within 1°C and communicates its temperature data via an industry-standard System-Management Bus (SMBus) interface. It operates at 2.25V in the -40° to +125°C range, programmable with 10 different conversion rates from 0.0625 to 32 conversions/s and four different resolutions (9-, 10-, 11- or 12-bit).

This allows the sensor to be easily designed into a wide range of consumer and professional equipment including solid-state drives, large display backlights, smart batteries, servers and routers, telecom and Internet infrastructure, and e-readers. The chip also feature interrupt and thermostat alarms. It comes in a choice of 6-pin 2x2mm UDFN-6L leadless package or a leaded SOT23-6L package.
