PMIC reduces wearable solution size by 50%

Designers of primary cell wearable medical and fitness applications can now reduce solution size by 50% and extend battery life with the MAX20310 ultra-low quiescent current (IQ) power management integrated circuit (PMIC) – according to Maxim.

The wearable PMIC is said to support low input voltages of 0.7 to 2V for high-energy density battery architectures such as zinc air and silver oxide, as well as the more common Alkaline battery architecture.

Using a single-inductor multiple-output (SIMO) dual buck-boost architecture, the MAX20310 integrates four power outputs from a single inductor each with ultra-low quiescent current performance.

This high integration is claimed to reduce solution size by half over comparable discrete solutions, consuming more than 40% less quiescent current and improving battery life.

The MAX20310 is suitable for applications such as non-rechargeable medical patches, environmental and equipment monitoring, and discrete sensors for the IIoT.

Operating over temperatures ranging from -40°C to 85°C, the MAX20310 is available in a 1.63 x 1.63mm wafer-level package.
