Tiny Power Management IC from Analog Devices Charges Wearables and Hearables Four Times Faster
WILMINGTON, Mass., Sept. 21, 2021 /PRNewswire/ -- The new MAX77659 single-inductor multiple output (SIMO) power management IC (PMIC) with integrated switch-mode buck-boost charger from Analog Devices, Inc. charges wearables, hearables and Internet of Things (IoT) devices faster and in less space than any other PMIC available today. The MAX77659 SIMO PMIC delivers over four hours of play time after a short, ten-minute charge, and uses a single inductor to power multiple rails, reducing the bill of materials (BOM) by 60 percent and shrinking total solution size by 50 percent.
The MAX77659 SIMO PMIC integrates a switch-mode buck-boost charger and three independently programmable buck-boost regulators, all sharing a single inductor to minimize total solution size. The regulators extend battery life by operating at 91 percent efficiency during moderate to heavy load conditions while consuming only 5µA of quiescent current during light load conditions. The MAX77659 SIMO PMIC supports autonomous headroom control, which reduces heat dissipation by minimizing the voltage drop while providing enough headroom to regulate the charging current.
"Analog Devices' SIMO product technology shrinks size and boosts performance in the smallest of hearable and wearable devices," said Roger Yeung, Executive Business Manager for the Battery Power Solutions Business Unit at Maxim Integrated®, now part of Analog Devices. "The MAX77659 brings the 'on-the-go' lifestyle to the next level by minimizing plug-in time and maximizing play time. The MAX77659 PMIC frees up board real estate to pack in additional features such as expanded memory storage, location tracking and vital sensing demanded by today's portable consumer and medical devices."
