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.

The smart power IC is delivered in a QFN20 power package with heat slug.
