Atmel Announces Extremely Flexible Airbag System Power Supply IC

Atmel announces a new monolithically-integrated ATA6264 airbag system power supply IC especially suited for high-end automotive airbag applications.

Broadest Set of Functionalities, Highest Accuracy, and Customer Programmability

The ATA6264 handles the voltage supply for complete airbag systems with programmable voltage levels. Communication with the microcontroller is carried out via a 16-bit SPI, while two ISO9141 interfaces enable the communication with diagnostic testers; one of these interfaces can be customer-programmed as a LIN interface.

The voltage supply section of the ATA6264 consists of a boost converter with adjustable voltage, two buck converters and a linear regulator that can be customer-programmed. This flexibility allows the user to adapt the ATA6264 to the needs of different system requirements and thus simplifies stocking issues. The new device, manufactured in high-voltage 0.8-um BCD technology, provides a rich set of features not available from any other competitive device.
