Battery protection controller targets smartphones & tablets
The LC05111CMT, a Lithium-ion battery protection controller from ON Semiconductor, incorporates controller and driver functions in a single circuit. Targeting smartphones and tablets, the controller enables high-precision current control without using a current detection resistor.
This current control reduces charging time by enabling higher charging current. Detection circuits and detection delay circuits prevents batteries from over-charging, over-discharging, over-current discharging, and over-current charging. Component count is reduced due to the high level of integration, which in turn reduces 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 priced at $1.00 USD in quantities of 10,000 units.
