MP26057 28V, 1A Linear Li-lon Travel Charger With Trickle Charge and Timer The Future of Analog IC Technology DESCRIPTION FEATURES The MP26057 is a linear, high performance Complete Solution for Charging Single-Cell single cell Li-Ion or Li-Polymer battery charger. Lion-Ion Battery By integrating high voltage input protection into Input Surge Up to 28V the charger IC, the MP26057 can tolerate an Wide Input Operating Range 3.5V 7V input surge up to 28V. Adapter or USB Input Programmable Charge Current: 200mA to 1A The device features constant current (CC) and Programmable Timer constant voltage (CV) charging modes with Termination and Auto-Recharge programmable charge currents (200mA to 1A), current blocking and trickle charge. The other 0.75% V Accuracy over Temperature BATT features include the programmable battery full <1A Battery Reverse Current threshold, termination and auto-recharge. 125A Standby Current from V IN MP26057 provides charger status indication to Battery Temperature Monitoring drive red and green LEDs (tri-color indication). Automatic Die Temperature Limiting Fault and Charge Status Indicators For guaranteed safe operation, the MP26057 Soft-Start to Limit Inrush Current limits the die temperature to a preset value Tiny 3mm x 3mm QFN Package when the device is heated up due to limited PCB space. Other safety features are battery APPLICATIONS temperature monitoring, and programmable timer to prevent prolonged charging a dead Cell Phones battery. Digital Cameras Smart Phones MP26057 is available in a 10-pin 3mm x 3mm PDAs DFN package. MP3 Players All MPS parts are lead-free, halogen free, and adhere to the RoHS directive.
