SAN JOSE, Calif., March 25, 2019 /PRNewswire/ -- With
automotive camera modules becoming increasingly smaller, designers
can now utilize the ultra-compact MAX20049 power management
IC from Maxim Integrated Products, Inc. (NASDAQ: MXIM), which
integrates four power supplies into a tiny footprint. In addition
to being the most compact power management IC for vehicle camera
modules, it delivers the highest efficiency on the market today.
The MAX20049 offers many options to support various output
voltages, while also providing fault mitigation by flagging faults
and shifts in output voltages.

Automotive camera modules tend to be size-constrained, so
designers are constantly in search of a power management solution
that can pack the necessary power and functionality into a small
form factor. The 4-channel MAX20049 power management IC is almost
30 percent more compact than competitive solutions and offers the
highest efficiency among other quad-power power management ICs in
its class. It offers many options to support modules that need
various output voltages for different mixes of sensors and
serializers, enabling designers to make changes in layout as needed
or to fine-tune the IC to meet specific application requirements.
The MAX20049 provides fault mitigation, a feature required by
designers to help flag faults and shifts in output voltages to
ensure that the cameras are working as needed.
Key Advantages
- Smallest Solution Size: has a PCB footprint that is
almost 30 percent smaller than that of the closest competitor
(38mm2 compared to 53.3mm2)
-
- 4 outputs (dual bucks and dual LDOs) in a 3mm x 3mm QFN
package
- Protection unavailable in competitive products include
over-voltage protection, under-voltage lockout, external power good
(PGOOD) signal and cycle-by-cycle current limit
- Highest Efficiency: system efficiency at full load is 74
percent (versus 69 percent for discrete automotive solutions)
-
- Thermal performance plus high efficiency contributes to overall
optimized performance
- Flexibility: the dual buck converters and low-noise LDO
support a wide voltage input range from 4V to 17V, enabling
power-over-coax (POC), typically from 8V to 10V. There is also an
option of using one of the buck converters as an intermediate
supply for generating typical sensor + serializer rails
-
- Optimizes thermal performance and minimizes coax inrush current
at startup
- Flexible sequencing and fixed output voltages supporting
various image sensors
- Fault Mitigation: flags faults and shifts in
output voltages to ensure cameras are working as intended
-
- Once an over- or under-voltage signal is detected, the PGOOD
pin will assert low
- Cycle-by-cycle current limit implemented by the respective
converter if either output is shorted
- Low Noise: spread spectrum and 2.2MHz switching
frequency mitigates electromagnetic interference (EMI) to meet
CISPR low-noise specifications
Commentary
- "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."
