Integrated Lithium-ion Battery Protection Controller
ON Semiconductor has announced a 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. 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.
