Features

• Six Connections for Series-resonant LF Coil Antennas

• Drives up to 1A Peak Current on the First Three Channels and up to 700 mA Peak on

the Second Three, Largely Independent of the Battery Voltage

• On-off-keyed Data Modulation with up to 6 kbit/s

• Sinusoidal-like Output Signal for Superior EMC Behavior

• 20 Selectable Steps for Current Regulation for Field Strength Measurement (RSSI)

• Output Driver Stages are Protected Against Electrical and Thermal Overload

• Very Low Power-down Current Consumption

Antenna Driver

for Multiple

Antennas

• SPI Interface for Easy Microcontroller Bus Connection

• LF Data Buffer to Minimize Microcontroller’s CPU Load During a Data Transmission

• Small Outline Package: QFN48, 7 mm × 7 mm

1. Description

The ATA5279N is an LF coil driver IC intended for passive entry/-go (PEG) systems. It

can drive up to six low-frequency-antennas (i.e., coils) to provide a wake-up and ini-

tialization channel to the key fob.
