The ATA5275-PGPI from Microchip Technology is an integrated 1.5A peak current BCDMOS antenna driver IC specifically designed as a 125 kHz wake-up channel transmitter for Tire Pressure Measurement (TPM) applications.
This IC is capable of generating a magnetic LF field in conjunction with an antenna coil to transmit data and power to a receiver. It features a frequency tuning range from 100 kHz to 150 kHz and supports LF baud rates up to 4 kbaud with ASK modulation. The device includes automatic antenna peak current regulation and a self-tuning oscillator for antenna resonant frequency adaptation.
With a power supply range of 8V to 24V, the ATA5275-PGPI operates reliably within automotive temperature ranges of –40°C to +105°C. It is supplied in a 20-QFN-EP (5x5) package suitable for surface mounting, requiring fewer external components due to its high integration level.
Key features include bi-directional single wire interface, low power standby mode (< 50 µA), and integrated antenna driver diagnosis for peak current, antenna frequency, and battery voltage monitoring. An integrated 5V regulator can supply external loads up to 10 mA.
