MP2611GL-P

The MP2611GL-LF-Z is a monolithic switching charger with built-in power MOSFETs for a single-cell Li-Ion battery pack. It achieves up to a 2A-charge current that can be programmed through an accurate sense resistor over the whole input range. It can operate from separate inputs for USB or AC adapter: For USB input, the input current limit can be programmed to 500mA and 900mA through the USBM pin to cover both USB2.0 and USB3.0 standards.  The MP2611GL-LF-Z regulates the charge current and battery voltage using two control loops to realize highly accurate constant-current charge and constant-voltage charge. A 100% duty cycle can be achieved when battery voltage is close to the input voltage due to the high-side P-Channel MOSFET.  Battery charge temperature and charging status are always monitored for each condition. Two status-monitor output pins indicate the battery charging status and input status. The MP2611GL-LF-Z also features internal reverse-blocking protection.  The MP2611GL-LF-Z is available in a 3mm x 4mm QFN14 package.
