Description
The circuit is an integrated BCDMOS antenna driver IC dedicated as a transmitter for
Passive Entry/Go (PEG) car applications and for other handsfree access control
applications.
It includes the full functionality to generate a magnetic LF field in conjunction with an
antenna coil to transmit data to a receiver in a key fob, card or transponder. The trans-
mission can be controlled via an one wire I/O interface (DIO) by an external control
unit.
