EV2607DL-00A Monolithic Power Systems

EV2607DL-00A Linear Li-Ion Battery Charger With System Power Path Management Evaluation Board The Future of Analog IC Technology DESCRIPTION FEATURES The EV2607DL-00A is an evaluation board for 12V maximum Voltage for the input source the MP2607, a linear, high-performance single Selectable Input Power Sources from AC cell Li-Ion battery charger integrated system Adapter or USB Port power path management. It takes power input Programmable Charge Current from either AC adapter or USB port to power the Built-in current limit for USB port system and charge the battery independently. Complete Power Path Management for Simultaneously Powering the System and The charger section features trickle charge, Charging the Battery. constant current (CC) and constant voltage (CV) 0.75% V Accuracy charging modes with programmable charge BATT current, charging termination and charge status. Thermal Protection Fault and Charge Status Indicator The system power path management function Built-in Timer for Charge Termination ensures continuous supply to the system. It features a low drop-out regulator from input to APPLICATIONS system and a switch from battery to system. If Smart Handheld Devices the input is valid, the power path management Cell Phones, PDAs, MP3 Players separates charging function and powering Digital Cameras, GPS system load. If the input is removed, the system Handheld Test Equipment load will be powered by battery.
