Linear LiFePO Battery Charger with 4 Power Path and USB Compatibility in LFCSP Data Sheet ADP5063 FEATURES GENERAL DESCRIPTION Default charging termination voltage at 3.6 V The ADP5063 charger is fully compliant with USB 3.0 and the Fully compatible with USB 3.0 and USB Battery Charging 1.2 USB Battery Charging 1.2 Compliance Plan Specification, and Compliance Plan Specification enables charging via the mini USB VBUS pin from a wall charger, Operating input voltage from 4 V to 6.7 V car charger, or USB host port. Tolerant input voltage from 0.5 V to +20 V (USB VBUS) The ADP5063 operates from a 4 V to 6.7 V input voltage range but 2 Fully programmable via I C is tolerant of voltages up to 20 V, thereby alleviating concerns about Flexible digital control inputs USB bus spikes during disconnection or connection scenarios. Up to 2.1 A current from an ac charger in LDO mode The ADP5063 features an internal field effect transistor (FET) Built-in current sensing and limiting between the linear charger output and the battery. This permits As low as 55 m battery isolation FET between battery and battery isolation and, therefore, system powering under a dead charger output battery or no battery scenario, which allows immediate system Thermal regulation prevents overheating function upon connection to a USB power supply. Compliant with JEITA1 and JEITA2 Li-Ion battery charging temperature specifications Based on the type of USB source, which is detected by an external SYS EN flag permits the system to be disabled until battery is at USB detection chip, the ADP5063 can be set to apply the correct the minimum required level for guaranteed system start-up current limit for optimal charging and USB compliance. 4 mm 4 mm LFCSP package The ADP5063 has three factory-programmable digital input/out- put pins that provide maximum flexibility for different systems. APPLICATIONS These digital input/output pins permit a combination of features, Single cell lithium iron phosphate (LiFePO4) portable such as input current limits, charging enable and disable, charging equipment current limits, and a dedicated interrupt output pin.
