Nanopower PMICs maximize battery and minimize board area

Dialog Semiconductor, a provider of custom and configurable power management, AC/DC power conversion, charging and Bluetooth low energy technology has unveiled its first fully-integrated nanopower PMICs for IoT applications, the DA9070 and DA9073.

The new, more powerful PMICs build on the success of Dialog’s first nanopower offerings, further highlighting how Dialog has pushed the boundaries of its PMIC technology to improve low-power IoT applications.

Today’s ‘always-on’ IoT devices such as fitness trackers, smartwatches and smart home products are expected to spend less time tethered to a charger, but expanding feature sets present new challenges to battery life. With board area already at a premium for engineers, new power management solutions are increasingly favored over increasing battery capacity.

Dialog’s new DA9070 and DA9073 nanopower PMICs have been developed to meet this growing demand. The PMICs extend battery life by drawing < 1uA quiescent current for each of its step-down regulators that power always-on components within the system, and combine all key power management functions to reduce board area by 25 percent compared to discrete regulators. Developers also have the option of creating a battery fuel gauge solution with the DA9070, using the integrated voltage and current monitors.

While other solutions on the market may integrate a handful of functions, Dialog’s new nanopower PMICs provide system designers an all-in-one power management solution. By doing so, the PMICs not only help extend battery life for IoT devices, but also minimize valuable board area for developers.

“As consumer demands continue to push design boundaries, system designers are now faced with a complex challenge of extending battery life even further while adding new feature sets, all in a small form factor,” said Udo Kratz, Senior Vice President and General Manager of Mobile Systems Business Group at Dialog. “Dialog’s first fully-integrated nanopower PMICs build on our expertise in power management and IoT connectivity to arm engineers with a compact, powerful solution that solves these challenges while reducing overall form factor of the system for wearables and other IoT devices.”
