ATA5283 - Interface IC for 125 kHz Wake-up Function

Description

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.

Features

  • Wake-up Function for a Microcontroller with Preamble Detection 1 mVrms Sensitivity 1 µA Standby Current Power Supply: 2 V to 3.8 V Baud Rate: up to 4 kbps (ASK Modulation) Operation Temperature: up to 125°C Withstands +175°C Few External Components.

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.
