MP2696A 2 I C-Controlled, Single-Cell Switching Charger with Power-Path Management and 3.6A Boost Output DESCRIPTION FEATURES The MP2696A is a highly integrated, flexible, 4.0V to 11V Operation Voltage Range switch-mode battery-charging, power-path Up to 16V Sustainable Input Voltage management device designed for a single-cell 500mA to 3.6A Programmable Charge Current Li-ion and Li-polymer battery to be used in a wide 3.6V to 4.45V Programmable Charge range of portable applications. Regulation Voltage with 0.5% Accuracy 100mA to 3A Programmable Input Current The MP2696A integrates three battery-charging Limit with 10% Accuracy phases: pre-charge, constant-current, and Minimum Input Voltage Loop for Maximum constant-voltage charge. This device also Adapter Power Tracking manages the input power source through input current limit regulation and minimum input Ultra-Low 25A Battery Discharge Current in Idle Mode voltage regulation. Boost Converter w/ Up to 3.6A Output Current: The MP2696A can switch to boost mode to o Programmable Output Current Limit Loop generate the system power output from the o Programmable Boost Output Voltage battery. o USB Output Cable Compensation The MP2696A has an integrated IN to SYS pass- o Programmable Inductor Peak Current through path to pass the input voltage to the Limiting system. Comprehensive Safety Features 2 o Fully-Customizable JEITA Profile with Using an I C interface, the host can flexibly Programmable Temperature Threshold program the charge and boost parameters. The o Charge Safety Timer device operating status can also be read in the o Input Over-Voltage Protection registers. o Thermal Shutdown Safety features include SYS short-circuit o SYS Over-Current and Short Protection protection, input over-voltage protection, battery Analog Voltage Output IB Pin for Battery under-voltage protection, thermal shutdown, and Current Monitoring JEITA battery temperature monitoring.
