ON Semiconductor Introduces Integrated Lithium-ion Battery Protection Controller for Smartphones and Tablets

LC05111CMT helps reduce charging time of portable electronics with high-precision control of charge/discharge current

TOKYO — (BUSINESS WIRE) — July 22, 2014 — ON Semiconductor (Nasdaq: ONNN), driving energy efficiency innovations, has announced a new Lithium-ion battery protection controller for smartphones and tablets. The highly integrated LC05111CMT utilizes analog circuit technology, MOSFET technology, and advanced packaging expertise to incorporate controller and driver functions in a single circuit.

The LC05111CMT enables high-precision current control without using a current detection resistor. This current control reduces charging time by enabling higher charging current. The device includes highly accurate detection circuits and detection delay circuits to prevent batteries from over-charging, over-discharging, over-current discharging and over-current charging. The high level of integration reduces component count, and therefore required board space, in the space-constrained battery pack.

“There is a clear requirement for the more accurate battery current control and small package in advanced portable devices,” said Ikuya Kawasaki, general manager of the Intelligent Power Solution division at ON Semiconductor. “The LC05111CMT combines technologies to deliver a physically small, yet functionally innovative device that helps reduce charging time and provides multiple levels of protection for the battery charging circuit.”


LC05111CMT is offered in a Pb-free and Halide-free WDFN-6 package, and is budgetary priced at $1.00 USD in quantities of 10,000 units.
