ATA5282 Ultra Low Power 125 KHz 3D - Wake-up Receiver With RSSI

The ATA5282 is a 125-kHz ultra low power receiver IC with three input channels for Passive Entry Go applications. It includes all circuits for an LF wake-up channel. The three sensitive input stages of the IC Amplifier demodulate and measure the input sig- nal from the Antenna coils. The Microcontroller Interface of the IC outputs the data signal as well as the measured RSSI values. During standby mode, the header detec- tion unit monitors the incoming signal and generates a wake-up signal for the Microcontroller if the IC receives a valid 125-kHz Carrier signal.
