Catalyst enters temperature sensor market

Catalyst Semiconductor has unveiled its first device in a line of temperature sensors.

The CAT6095 is a 12-bit digital output temperature sensor available in a 0.55mm-tall UDFN package for DDR3 memory module applications in high-speed PCs and laptops, environmental control systems and industrial process control equipment.

The UDFN package provides accurate temperature monitoring in a 30 per cent lower profile package compared to standard 2 x 3 x 0.8mm TDFN packages.

The CAT6095 is compliant to Jedec specification JC42.4, providing +/-1C temperature sensing accuracy from +75C to +95C, plus +/-3C accuracy from -20C to +125C, across the device's entire supply voltage range (3 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 signalled on the open-drain Event pin.

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.
