Maxim’s broad portfolio of high-performance ICs facilitates the implementation of infotainment architectures with value-added features that are both relevant to current consumer offerings and robust enough for the automotive environment. 

For video transmission, Maxim’s LVDS transceivers significantly reduce solution costs while delivering rugged ESD protection, DC balancing and enhanced EMI performance. The MAX9257/ MAX9258 bi-directional serializer/deserializer (SerDes) chipset eliminates the need for a CAN or LIN interface in automotive video applications and allows the use of lower cost cables and connectors. Forming a complete digital video link over a single differential line or twisted-wire pair, the chipset converts up to 18 bits of parallel data into a high-speed serial data stream.

Rear-seat entertainment systems benefit from Maxim’s MAX7461 singlechannel loss-of-sync (LOS) alarm. This device provides composite video sync detection in NTSC, PAL and SECAM standard-definition television (SDTV) systems. The MAX7461 device’s advanced detection circuitry delivers robust performance by preventing false LOS alarms due to noise, thereby eliminating the microcontroller required by traditional LOS monitoring systems.

The MAX2170/MAX2171 devices allow design engineers to support digital radio (DAB), mobile TV (T-DMB) and FM signals with a single tuner. These tuners achieve a high level of component integration, enabling low-power, tuner-on-board designs.

The MAX15004/MAX15005 power-supply controllers integrate output overvoltage protection to prevent damage to vacuum fluorescent displays (VFDs). They operate from an automotive input-voltage range of 4.5 to 40 V (load dump), and support an input voltage down to 2.5 V after startup if VCC is supplied by an external bias voltage.

For backlighting LCD applications, the MAX16826 high-brightness (HB) LED driver provides design engineers with an extremely rugged and flexible solution. This device can withstand load-dump transients up to 40 V and can operate under cold-crank conditions. Additionally, it features an I²C interface to minimize system implementation cost and enhance flexibility. The I²C interface allows dynamic programming of the switching regulator’s output voltage and the amplitude of the LED current in each channel. This capability maximizes the power efficiency of the LED driver circuit and allows the system manufacturer to accommodate LED binning variations.

The MAX15006/MAX15007 low-dropout linear regulators are ideal solutions for always-on applications. These devices operate from an input voltage of 4 to 40 V, deliver up to 50 mA of output current and consume only 10 µA of quiescent current at no load. An internal p-channel pass device keeps the quiescent current as low as 90 µA (typical) even at full load.
