The Microchip Technology ATA5279C-WGQW is an antenna driver IC specifically designed for passive entry and go (PEG) systems. It is capable of driving up to six low-frequency coil antennas, providing a wake-up and initialization channel to key fobs.
This IC operates at a frequency of 125kHz and features an SPI interface for easy microcontroller connection. It supports passive entry/start functionality and is housed in a 48-VFQFN exposed pad package, measuring 7mm x 7mm. The device operates within a voltage range of 4.1V to 4.8V and can withstand operating temperatures from -40°C to 145°C.
Key electrical characteristics include peak current drive capabilities of up to 1A on the first three channels and 700mA on the second three. It supports on-off-keyed data modulation up to 5.7 Kbit/s with a sinusoidal-like output signal for superior EMC behavior. The ATA5279C-WGQW also includes 20 selectable steps for current regulation for field strength measurement (RSSI) and output driver stages protected against electrical and thermal overload. It offers very low power-down current consumption and an LF data buffer to minimize microcontroller CPU load during data transmission.
Mounting is via surface mount technology. The 48-VQFN (7x7) package is suitable for compact designs.
