Cxle86163 series is a multifunctional linear step-down controller with charge and discharge protection. Only a few external components are needed, which is suitable for the application of portable products of lithium iron phosphate battery.
The cxle86163 circuit uses a high-performance, low-power reference circuit structure, and introduces correction technology in the production to ensure the high output accuracy and low temperature drift of the output voltage.
Cxle86163 has overcharge and over discharge protection function, over temperature current compensation, output linear constant current, output current can be set through external resistance; at the same time, it can switch mode (half bright, full bright, off) through light touch switch connected by SDET pin. Semi bright brightness adjustment (25% ~ 75%, step 6.25%) can be realized through internal adjustment
