|STMicroelectronics STTS751 digital temperature sensor (DTS) is mounted on a circuit board to feed back accurate temperature data, allowing a system to manage its temperature, for example, by activating a cooling fan or shutdown circuitry.
Measuring 2 x 2mm, this sensor is smaller than previous generation sensors and has an ultra-low 50µA operating current, a power-saving 3µA standby current, and a one-shot mode that makes the device ideal for battery-powered applications. 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. 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.
