Extended battery life

Maxim Integrated Korea announced the 'MAX20310', an ultra-low standby current power management integrated circuit (PMIC). The MAX20310 reduces solution size by 50% and extends battery life.

The MAX20310 wearable PMIC supports low input voltages in the range of 0.7 to 2 V in new high-energy density battery architectures such as air-zinc, silver oxide, and alkaline.

When designing wearable medical and fitness applications, various factors such as ultra-small form factors and extended battery life must be considered. Designers require separate components to build sophisticated power trees. These power trees occupy board space, consume high standby current, and drain battery life when the device is in sleep mode. Rechargeable solutions can also present additional problems, as bacteria may remain on contacts, mounting points, and charging ports.

The MAX20310 uses a new SIMO (Single-Inductor Multiple-Output) architecture to integrate four outputs with ultra-low standby current performance from a single inductor. This high level of integration extends battery life by reducing size by half and standby current consumption by more than 40% compared to similar discrete solutions. Additionally, it is suitable for non-rechargeable medical patches for environmental and equipment monitoring, as well as for standalone sensors for industrial IoT. It operates over an operating temperature range of -40°C to +85°C and is available in a small 1.63mm x 1.63mm wafer package.

Frank Dowling, Director of Industry and Healthcare at Maxim Integrated, said, “The newly launched ultra-small wearable PMIC is suitable for devices that must be worn 365 days a year and prioritizes patient comfort. It also extends battery life, which is an essential element of wearable devices.”
