... Power Saving/Low Current Consumption for Wake-Up Systems 1. Description The ATA5276 is an integrated 1.5A peak current BCDMOS antenna driver IC dedi- cated as a 125 kHz wake-up channel transmitter for TPM applications. It includes the full functionality to generate a magnetic LF field in conjunction with an antenna coil to transmit data and power to a receiver. The transmission can be con- trolled via a one wire I/O-interface by an external unit ...

... General Description The ATA5276 is a 125-kHz transmitter IC dedicated to driving 125 kHz LC antenna tanks, for the wake-up channel in Tire Pressure Measurement (TPM) applications or various power saving Industrial wake-up applications.. It includes a control logic with VCO which generates the 125 kHz signal for the output driver stage ...

... Standby Mode and Wake-up After power-on-reset, the ATA5276 is in standby mode. For minimum power consumption, only the internal 5V supply and the DIO line interface are active. The IC can be activated by the exter- nal control unit via the serial interface. The DIO line is called logic high pulled up to the VDIO voltage level ...

... Transmission Mode 4.3.1 ASK Modulation For the transmission of a wake-up signal or data to a receiver, the ATA5276 generates a antenna resonance synchronized signal at the antenna driver output (DRV pin). A connected LC antenna radiates a magnetic field. For the data transmission the field can be 100% amplitude modulated by the DIO interface input ...
