TE CONNECTIVITY TSYS03 Digital Temperature Sensor
TE Connectivity’s Measurement Specialties TSYS03 digital temperature sensors provide fast and accurate temperature sensing with two industry-standard miniature package options and low power consumption.
The sensors work by generating a voltage generated across a highly durable temperature sensing diode with a highly linear response. An onboard ASIC converts voltage to a digital value to send over the I2C interface, which operates at up to 1MHz. The sensor has a fixed primary I2C address, but a secondary I2C address can be programmed in non-volatile memory to use multiple sensors on the same bus, which results in smaller solution size and more address flexibility compared to using pin-strapping to set the secondary address. The device also offers low power consumption, with an active current less than 5µA and standby current less than 0.3µA, making the TSYS03 ideal for mobile and battery-powered devices. Their small size and low power consumption also come with excellent performance.
The sensors have a ±0.5°C high accuracy range from 0°C to +60°C, and the high accuracy range can be factory adjusted by request. For the full -40°C to +125°C operating temperature range, the sensors offer ±0.01°C resolution.
TE offers the TSYS03 in miniature packages that have a low thermal mass for a fast response to temperature changes. The smallest and lowest profile option is a 1.5mm x 1.5mm x 0.38mm XDFN6. The sensors are also offered in a 2.5mm x 2.5mm x 0.75mm TDFN8 package. With a die attach pad to connect to PCB copper plane for applications measuring PCB temperature, this can also be left disconnected for measuring surrounding air temperature or other mediums. The devices are suitable for a wide range of consumer, HVAC, industrial, automotive, and medical applications.
