Observe precautions for handling. 125 kHz Transmitter IC for TPM ATA5275 The ATA5275 is an integrated 1.5A peak current BCDMOS antenna driver IC dedicated as a 125 kHz wake-up channel transmitter for TPM applications. It includes the full functionality to generate a magnetic LF field in conjunction with an antenna coil to transmit data and power to a receiver. The transmission can be controlled via a one wire I/O-interface by an external unit. The smart power IC is delivered in a QFN20 power package with heat slug. The ATA5275 is a 125-kHz transmitter IC. It is dedicated to driving 125 kHz LC antenna tanks, specifically for the wake-up channel in Tire Pressure Measurement TPM applications. It includes a control logic with VCO which generates the 125 kHz signal for the output driver stage. A phase lock circuit regulates the driver output frequency on the antenna resonance frequency, achieving a maximum field strength on the antenna. The driver duty cycle is regulated and stabilizes the antenna current for a wide supply voltage range. The IC can be controlled by a microcontroller or ECU via the one wire bi-directional interface. It is used for the data transmission and to indicate errors. For the data transmission ASK modulation is used. The antenna signal is modulated by the DIO interface line. The IC has a build in diagnosis function and detects detuning and broken or short wire of the antenna circuitry. If a failure is detected the IC indicates it by an error signal via the DIO line. The integrated 5V regulator can be used externally for a load up to 10 mA.
