Analog Devices Multi-Voltage Monitors and Sequencers Deliver Industry
Leading Accuracy
ADI’s four-channel voltage monitor and
sequencer ICs measure minute changes in processor voltage levels to
prevent data loss and failures in high-availability communications
infrastructure applications
NORWOOD, Mass. (Business Wire EON) April 15, 2008 --
Analog Devices, Inc. (NYSE: ADI) is expanding its power management
offerings with the industry’s most accurate
low-voltage monitoring and sequencing ICs. Leveraging ADI’s
precision analog design techniques, the new ADM1184 and ADM1186 quad
voltage-monitor and sequencer ICs are twice as precise as competing
devices, offering best-in-class accuracy (<±0.8%).
The ADM1184 and ADM1186 also complete the industry’s
only monitor and sequencer family to deliver <±1%
accuracy for 2 to 12 supplies. The new ICs are designed for today’s
advanced data and telecommunications infrastructure equipment, which is
driven by extremely powerful processors with ever-lower core-voltage
supplies. With unprecedented accuracy, the ADM1184 and ADM1186 precisely
monitor processor cores to ensure they operate within voltage tolerance
specifications, allowing power and system engineers to maximize system
uptime and optimize system performance.
“As the operating level of ASICs, DSPs, FPGAs
and other processing cores drops to 1 volt and below, the ability to
reliably monitor low-voltage core supplies is becoming more difficult,”
said John Perzow, marketing director for fixed power products, Analog
Devices. “This creates the potential for
under-voltage conditions that can result in lost data and system failure.”
By improving accuracy to less than ±0.8
percent, the ADM1184 and the ADM1186 meet today’s
more demanding processor monitoring requirements, which promote safer,
more reliable and better optimized system operation in sensitive,
high-availability applications, such as wireless communications
equipment. Competitive multi-voltage monitors and sequencers typically
achieve a >±
1.5% accuracy level, which does not meet modern processor requirements
for monitoring low-voltage core supplies with a low tolerance and narrow
band of operation.
With industry-leading accuracy, a high level of functional integration,
and a small package size, the ADM1184 and ADM1186 incorporate four
precision comparators with 0.6-V references to monitor separate voltage
rails. The new ICs operate on a 2.7-V to 5.5-V power supply and include
four inputs that can be programmed to monitor different voltage levels
using external dividers. Additionally, the ADM1186 allows power-up and
power-down sequencing in hardware, eliminating the need for software
support and further increasing system reliability by ensuring that the
voltage supply rails are powered up and down in the correct order and
within tolerance.
Availability and Pricing
The ADM1184 and ADM1186 are available now in production quantities. The
ADM1184 is priced at $2.39 per unit in 1000-piece quantities and comes
in a space-saving 10-lead MSOP (mini-small-outline package). The
ADM1186-1 is priced at $3.80 per unit in 1000-piece quantities and comes
in 20-lead QSSOP (quartersize small outline package). The ADM1186-2 is
priced at $2.98 per unit in 1000-piece quantities and comes in a 16-lead
QSSOP. Stand-alone and in-system application boards also are available
to facilitate product evaluation. For more information, visit www.analog.com/pr/ADM1184
