Dialog Extend Battery Life For “always-on” Connected Applications

News

Dialog Semiconductor, a provider of highly integrated power
management, AC/DC power conversion, charging, and Bluetooth low energy
technology, has unveiled its first nanopower PMICs, the DA9230 and DA9231.
Consuming only 750 nA of total input current with the buck enabled and under no
load conditions, the two new PMICs are the smallest of their class on the
market, enabling longer battery operating time and enhanced efficiency for
“always on" IoT applications.

With a predicted 12 percent annual increase in the number of
connected devices worldwide from 2017 to 2030 according to IHS1, consumer
demands for increased efficiency are growing, particularly when it comes to
battery life and functionality. However, engineers have faced challenges when trying
to balance small form factors with the need for greater battery life, often
resulting in devices with inefficient power management or limited battery
capacity.

Dialog’s DA9230 and DA9231 will enhance the battery life and
power efficiency of common IoT devices such as wearables, smart door locks,
portable medical devices and remote sensors. The PMICs improve battery life
with ultra-low quiescent current, high-efficiency and configurability, all
offered in a small footprint to fit into space-constrained applications. One of
the strongest features of DA9230 and DA9231 is the form factor, as the smallest
PMICs on the market when measuring up against other comparable chipsets. Other
PMICs on offer either lack multiple rails and I2C configurability in one chip,
or take up twice the size as Dialog’s offering.

Designed to support current and future platforms, the DA9231
features a 300mA buck together with a 100mA LDO and the DA9230 features a
standalone buck. For both devices, the buck regulator’s minimum output voltage
of 0.6V enables powering advanced 14 or 10 nm geometry SOCs.

With a minimum supply voltage of 2.5V, these devices are
also ready to support upcoming silicon anode battery technology.

“Our first nanopower offering, the most compact and efficient
PMICs we have created, exemplifies Dialog’s leadership position in the power
management space," said Paul Wheeler, VP Mobile Systems, Dialog Semiconductor.
“As IoT and wearable devices continue to flood the market and consumer demands
for extended battery life and additional functionality increase, these new
PMICs give designers the flexibility, space and power to improve always-on
battery-powered applications."
