FEATURES  
Output Stage Consists of Eight Programmable  
Half-Bridge MOSFET Drivers (Configurable in  
Half, Full, or Parallel Bridges) Which Deliver  
Modulated Current to Each Coil  
Divider Block Generates an Internal Frequency  
From the Input Clock (Main Controller); Used  
for the Internal Logic  
Sophisticated Failure Detection and Handling  
HTSSOP (PWP) 28-Pin Package  
Linear Mode Output: Generates a Sine Wave  
Voltage That is Controlled by the  
Microcontroller  
Operating Temperature Range:  
-40°C to +105°C  
Output Stage is Overload Protected for Short  
and Over Temperature  
APPLICATIONS  
Driver Control and Diagnosis Blocks Drive the  
Gates of the MOSFETS Via Data From the SPI  
Automotive Passive Start and Passive Entry  
Applications  
Antenna Diagnostics: Short to GND, Short to  
VBAT, And Open Load Via Current  
Measurement  
DESCRIPTION  
The low-frequency (LF) antenna driver is dedicated to automotive applications requiring passive entry or passive  
start operational control. It allows for up to eight dedicated drivers, consisting of MOSFET transistors. The device  
also incorporates sophisticated diagnosis, protection and monitoring features.
