The CAT6095 from Catalyst Semiconductor is the first device in a new line of temperature sensors.  The 12-bit digital output temperature sensor is available in an ultra-thin, 0.55mm height UDFN package for DDR3 memory module applications in high-speed PCs and laptops, environmental control systems and industrial process control equipment. 

The CAT6095 can also be used for general temperature sensing applications in networking equipment, cellular base stations and medical equipment. The UDFN package provides accurate temperature monitoring in a 30% lower profile package compared to standard 2 x 3 x 0.8mm TDFN packages.

The CAT6095 is compliant to JEDEC specification JC42.4, providing ±1°C temperature sensing accuracy from +75°C to +95°C and ±3°C accuracy from -20°C to +125°C, across the device’s entire supply voltage range (3.0 to 3.6V). 

It measures and records the system temperature approximately 10 times per second, with readings compared to three trigger limits stored in the internal memory registers. Readings can be retrieved by the host system via the I2C/SMBus interface, with over- and under-limit conditions signaled on the open-drain EVENT pin. 

In addition to the space-saving 2 x 3 x 0.55mm height UDFN package, the CAT6095 is also available in the standard 2 x 3 x 0.8mm TDFN package. Both packages contain an integrated backside metal pad for enhanced PC board thermal contact and faster sensing response time.
