LIN system basis chips

Atmel announced the availability of its ATA6622, ATA6624 and ATA6626 LIN system basis chips (SBCs) which comply with the LIN2.0 standard. Compared to stand-alone LIN transceivers, system basis chips include a voltage regulator plus a watchdog. The ESD protection is more than 8 kV. Applications include automotive comfort applications such as door modules, seat control or intelligent sensors, and powertrain applications such as engine control systems.

 

These ICs also provide several protective features such as over-temperature shut down and full protection against short circuits. The ATA622/24/26 also meet automotive qualification demands and can withstand transients according to ISO/TR 7637/1. In addition to the remote LIN bus wake-up, the ATA6622/24/26 offer two further wake-up options, a wake-up via the WAKE pin or via the KL15 pin. To enable very slow data communication, as required by specific applications, the ATA6626's time-out timer is deactivated.

 

ATA6622, ATA6624 and ATA6626 LIN SBC IC samples are available now in Pb-free QFN20 packages with pricing starting at US $0.99 each for 10k piece quantities.
