ATA5283P-6APJ
ATA5283P-6APJ Datasheet
The ATA5283 is a 125 kHz ultra-low power receiver used for the wake-up function of Tire Pressure Monitoring TPM application. The sensitive input stage of the IC amplifies and demodulates the carrier signal from the antenna coil to a digital output signal for a microcontroller. During the standby mode the preamble detection unit monitors the incoming signal and activates the wake-up output and the data output, if the IC receives a proper 125 kHz carrier signal.

| • Wake-up Function for a Microcontroller with Preamble Detection • 1 mVrms Sensitivity • 1 µA Standby Current • Power Supply 2V to 3.8V • Baud Rate up to 4 kbps ASK Modulation • Operation Temperature up to 125°C • Withstands +175°C • Few External Components Application • Tire Pressure Monitoring TPM The ATA5283 is a 125 kHz ultra-low power receiver used for the wake-up function of Tire Pressure Monitoring TPM application. The sensitive input stage of the IC amplifies and demodulates the carrier signal from the antenna coil to a digital output signal for a microcontroller. During the standby mode the preamble detection unit monitors the incoming signal and activates the wake-up output and the data output, if the IC receives a proper 125 kHz carrier signal. By combining the IC with an antenna coil, a microcontroller, an RF transmitter/transceiver, a battery, temperature- and pressure sensor, it is possible to design a complete Tire Pressure Monitoring system TPM .
