The portable PMIC supports a low input voltage of only 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
There are several factors to consider when designing for medical and fitness wearable applications, including the ultra-small form factor and battery life. However, designers often need discrete components to build a sophisticated power tree that can occupy precious motherboard space, draw significant current, and shorten battery life when the device is in standby mode. In clinical settings, there are additional challenges since rechargeable solutions include contacts, clips, and charging ports where germs can linger.
Utilizing a novel single-inductor multi-output (SIMO) architecture, the MAX20310 integrates four single-inductor power outputs with ultra-low quiescent current performance. This high integration reduces the solution size by half compared to comparable discrete solutions, consuming over 40% less current in standby mode and thus improving battery life. In clinical settings, primary cell architectures can create hermetically sealed units for safe disinfection between uses or even complete disposal to prevent patient-to-patient infection. The MAX20310 is ideal for applications such as non-rechargeable medical patches, environmental and equipment monitoring, and discrete sensors for the Industrial Internet of Things (IIoT). Working in the temperature range of -40 to +85 degrees Celsius, the MAX20310 is available in a small 1.63mm x 1.63mm WLP (Wafer-Level Package) package.
