STMicroelectronics has launched a novel temperature sensing device, the STTS751, for monitoring the temperature in electronic systems to ensure thermal protection to the devices.
The unique STTS751 sensor is fixed on a printed circuit panel to monitor precise temperature information and perform maintenance, by turning on a cooling system or arresting the circuit operation.
This improved sensor features a single-shot operation for battery operated devices and its calibration capacity falls within the range of 2 mm x 2 mm with low working current in the 50 µA and a standby power saving current of 3 µA. The single mode operation permits the activation of the sensor only upon the systems’ stimulation and produces precise readings instantly
The accuracy of the temperature sensor, which operates digitally, is within 1°C and it uses the System-Management Bus (SMBus) interface for transmitting temperature information. This factor supports its incorporation in a wide variety of professional as well as consumer appliances such as large display backlights, smart batteries, e-readers, Internet infrastructure, servers and routers, telecom and solid-state drives.
