Driver Monitoring Systems Need a New Breed of IR-LED Drivers
Driver monitoring systems are appearing more frequently in modern automobiles. They must fit seamlessly within the automotive electronic system, creating the need for flexible, small, and efficient solutions. We review the IR camera system and discuss the shortcomings of a typical solution. Finally, we present the MAX20050 IR-LED driver as a solution. The IC is flexible, compact, efficient, has low EMI, and interfaces directly to the car battery.

Worried About Heat in Your I/O Module? No Need to Sweat

 

Worried About Heat in Your I/O Module? No Need to Sweat
The MAX22191 is an IEC 61131-2 compliant, industrial digital input (DI) device that translates a 24V digital industrial input to a 2.4mA (typ) current for driving optical isolators. Voltage thresholds and current levels in the MAX22191 are compliant with Type 1 and Type 3 inputs, while minimizing power dissipation.

Beat the Heat: Build a Compact, Multi-Standard Dual USB Charger

 

Beat the Heat: Build a Compact, Multi-Standard Dual USB Charger
USB ports in automotive charging applications must fit inside small spaces without overheating. The problem is exacerbated in the case of dual-port dedicated charging solutions, which must support two connectors without increasing component count and solution size. We review the shortcoming of a typical solution and show how MAX20047, a novel automotive-grade, small-footprint dual-port charger IC, overcomes the challenges of size and heat generation.
