Compact four-channel automotive power management IC for vehicle camera modules

28-03-2019 | Maxim | Automotive Technologies

With automotive camera modules becoming even smaller, designers can now use the ultra-compact MAX20049 power management IC from Maxim Integrated Products, which combines four power supplies into a tiny footprint. As well as being one of the most compact power management IC for vehicle camera modules, it provides one of the highest efficiency on the market today. The device provides many options to support various output voltages, while also providing fault mitigation by flagging faults and shifts in output voltages.

The power management IC is almost 30% more compact than competitive solutions and provides the highest efficiency among other quad-power power management ICs in its class. It gives many options to support modules that necessitate various output voltages for various mixes of sensors and serializers, allowing designers to make modifications in layout as required or to fine-tune the IC to meet specific application demands. The device gives fault mitigation, a feature needed by designers to help flag faults and shifts in output voltages to guarantee that the cameras are working as needed.

“We continuously look for integrated power devices that provide the required power source for image sensors while minimizing size in vehicle-based imaging designs,” said Tsutomu Haruta, deputy senior general manager, Sony Semiconductor Solutions Corporation. “Maxim’s power solutions would help enable multi-camera functionality and advanced driver safety systems in a small footprint.”

“We selected the MAX20049 due to its high integration, which aids in designing smaller boards – traditionally a challenge in designing cameras,” said Chris Day, vice president of Marketing, Ambarella. “Maxim has a stellar reputation within our Tier 1 customers for providing a complete automotive-grade solution for power and SerDes that include AECQ100 and ASIL-level certifications. Using reputable automotive-grade parts in our reference design ensures that customers can simply replicate the design, thereby reducing the overall risk in production.”

“Designers have increasingly demanding constraints to adhere to when designing for the tiny components that go into cars, such as cameras modules, which is why there is a growing demand for more advanced power management ICs,” said Chintan Parikh, executive business manager for the Automotive Business Unit at Maxim Integrated. “The MAX20049 meets ADAS design needs in terms of form factor, fault mitigation and power requirements, which translates to faster design cycles and quicker time to market.”
