Enabling designers to optimise power and battery life for wearable medical/fitness and IoT applications, the MAX14720 PMIC has been introduced by Maxim Integrated. Increasing battery life and achieving low power are common challenges faced by engineers when developing wearable and IoT products. The MAX14720 PMIC is suited for non-rechargeable battery (coin cell, dual alkaline) applications where size and energy efficiency are critical.

Integrating the functionality of five discrete devices - power switch, linear regulator, buck regulator, buck-boost regulator and monitor - the MAX14720 reduces the BOM and allows for much smaller form factor designs.

While most battery PMICs operate from 3V, the MAX14720 runs from a primary cell and operates down to 1.8V to reduce power consumption. The device's low quiescent current IP is critical for wearable applications since it can extend the runtime of the system significantly.

An electronic battery seal allows for a fully sealed housing and extends shelf life by effectively disconnecting the battery prior to initial power-up. Value added features such as push button input monitoring, power-up sequencing and voltage rail monitoring further reduce BOM cost and space.

Frank Dowling, Executive Business Manager, Maxim Integrated, commented: “Maxim has a strong position in the rechargeable wearables market. As a result, we have leveraged our expertise and IP for the non-rechargeable wearables market.”

Available in a 25-bump, 2.26x2.14mm WLP with a 0.4mm pitch, the MAX14720 operates over a temperature range from -40 to +85°C. Contact Maxim for pricing.
