Promote energy-efficient and innovative ON Semiconductor (ON Semiconductor) introduced a new lithium-ion battery protection controller for smartphones and tablets. The highly integrated LC05111CMT utilizes analog circuit technology, MOSFET technology, advanced package expertise and technology to integrate controller and driver functions in a single circuit.

The LC05111CMT achieves high precision current control without the need for a current sense resistor. This current control shortens the charging time by supporting a larger charging current. The device includes a high-precision current-sense circuit and a detection delay circuit to prevent overcharging, over-discharging, excessive current discharge, and excessive current charging. The high level of integration reduces the number of components, thus reducing the board space required in space-constrained battery packs.

Ikuya Kawasaki, General Manager, Intelligent Semiconductor Solutions Division, ON Semiconductor, said: "Advanced portable devices clearly require more accurate battery current control and small package. The LC05111CMT combines multiple technologies to provide small but functionally innovative devices to help reduce charging time And provide multiple levels of protection for battery charging circuits."

Package

The LC05111CMT is available in a lead-free and halide-free WDFN-6 package and is priced at $1.00 per unit in 10,000-piece quantities.
