The new sensor is smaller than previous-generation sensors, measuring 2 x 2mm, and has an ultra-low 50-microamp operating current, a power-saving 3-microamp standby current, and a one-shot mode that makes the device ideal 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. 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.
Key features of the STTS751:
* 2.25V operation from -40°C to +125°C
* Conversion time: 21ms (typical, at 10-bit resolution)
* Programmable, with 10 different conversion rates and four different resolutions
* 0.0625 to 32 conversions per sec
* 9-, 10-, 11- or 12-bit resolution
* Dual Alarms: interrupt and thermostat
* Slave addresses possible per device type
* SMBus 2.0 Alert Response Address (ARA) and Timeout support
