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, 2.26×2.14mm WLP with a 0.4mm pitch, the MAX14720 operates over a temperature range from -40 to +85°C. Contact Maxim for pricing.
