New Device Boasts Lowest Current Consumption and Smallest Size
June 24, 2003- Atmel® Corporation announced the availability of its new ultra low power ASK receiver IC. The ATA5283 provides the industry's best trade off in terms of minimum current consumption and maximum sensitivity. Furthermore, it is the smallest available device for 125 degree C applications, such as tire pressure monitoring.
The new IC is designed for use in tire pressure monitoring modules where it wakes up the TPM module and enables data programming during production and tire change during service. Remote triggering and programming is usually done in a distance of about 2 meters. Due to this, TPM systems are not based on short-distance triggering solutions but on LF receivers. The ATA5283 operates in the range of 2.0 V to 4.2 V over temperatures of -40 to 125 degree C. It can withstand environmental temperatures on battery supply up to 175 degree C for short intervals.
To comply with automotive manufacturers' standards, a TPM module must have a minimum life time of 10 years. Since the integrated battery in such modules cannot be replaced, low current consumption is a must for TPM applications. The LF receiver ATA5283 is constantly in standby listening mode and monitors for a signal originating from the car or from a base station. The device switches off the TPM module when it is not needed to extend the module's battery life time and wakes up the module only if a valid preamble has been detected. The ATA5283's current consumption in listening mode with a sensitivity of 1 mV rms is as low as 1 microampere typ., while competing products have current consumption at least 3 times highter.This combination is unique in industry.
