Maxim’s PMIC Reduces Solution Size By
50% for Wearable Medical and Fitness
Applications
Designers of primary cell wearable medical and fitness
applications can now significantly reduce solution size
by 50% and extend battery life with the MAX20310
ultra-low quiescent current (IQ) power management
integrated circuit (PMIC) from Maxim Integrated
Products, Inc. (NASDAQ: MXIM). The wearable PMIC
supports a low input voltage of just 0.7V for new high-
energy density battery architectures such as Zinc
Air and Silver Oxide, as well as the more common
Alkaline battery architecture. With personal and remote
monitoring gaining traction, reducing size and extending
battery life are critical benefits. For example, a report by
Allied Market Research projects that the global remote
patient monitoring market is expected to grow at a
compound annual growth rate (CAGR) of 17% to reach
$2.13 billion by 2022.1
There are several factors to consider when designing
for wearable medical and fitness applications, including
ultra-small form factor and longer battery life. However,
designers typically need discrete components to build
a sophisticated power tree which can take up precious
board space, consume high quiescent current, and burn
through battery life when the device is in sleep mode.
In clinical environments, there are additional challenges
since rechargeable solutions involve contacts, clips, and
charging ports where germs may linger.
Using a novel single-inductor multiple-output (SIMO)
architecture, the MAX20310 integrates four power
outputs from a single inductor each with ultra-low
quiescent current performance. This high integration
reduces solution size by half over comparable discrete
solutions, consuming over 40% less quiescent current
and improving battery life as a result. In clinical
environments, primary cell architectures can create
hermetically sealed units to safely disinfect between use
or even dispose of completely to inhibit patient-to-patient
infection. The MAX20310 is ideal for applications such
as non-rechargeable medical patches, environmental
and equipment monitoring, and discrete sensors for
industrial internet of things (IIoT). Operating over the
-40-degree Celsius to +85-degree Celsius temperature
range, the MAX20310 is available in a small, 1.63mm x
1.63mm wafer-level package (WLP).
Key Advantages
Small Solution Size: Available in a SIMO dual buck-
boost architecture with single external inductor; Reduces
solution size by 50% compared to discrete solutions
Versatile Architecture: Supports Zinc Air, Silver Oxide,
and Alkaline battery systems with low input voltage of
0.7V to 2V
Longer Battery Life: Consumes 40% lower quiescent
current during sleep or standby mode compared to
discrete solutions
Commentary
“This ultra-small wearable PMIC allows for patient
comfort, particularly when it comes to devices which
must be worn 24 hours a day, 7 days a week,” said Frank
Dowling, Director for Industrial & Healthcare at Maxim
Integrated. “It also improves active runtime for longer
battery life, another essential component for wearable
applications.”
“Maxim’s newPMIC is away to improve patient outcomes
through continuous monitoring, a trend which is rapidly
growing,” said Susie Inouye, Research Director and
Founder at Databeans.
