General 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 transmission can be controlled via an one wire I/O interface (DIO) by an external control unit.

Key Features

Programmable Driver Current Regulation Antenna Driver Stage for 1 A Peak Current LF Baudrates between 1 kbaud to 8 kbaud Integrated Oscillator for Ceramic Resonators Two Inputs for Push-button Switches Bi-directional Single-wire Interface Diagnosis Function and Overtemperature Protection Quick Start Control (QSC) for Fast Oscillation Build-up and Decay Timing Operatio.
