EVALUATION KIT AVAILABLE MAX14746/MAX14747 USB Detection with Smart Power Selector Li+ Chargers General Description Benefits and Features Flexible System Design to Operate with Any USB The MAX14746/MAX14747 are a series of USB charger Charger Source detectors with an integrated Smart Power Selector linear Compliant to USB Battery Charger Rev 1.2 charger solutions that provide a single-chip solution for Specification* charging and charger detection. Supports Proprietary USB Charging Sources, The MAX14746/MAX14747 charger detectors are compliant Including Apple to USB Battery Charger Detection Rev 1.2* and capable D+/D- Bias Voltage Supported of detecting multiple USB battery-charging methods, Easy to Implement Li+ Battery Charging including Standard Downstream Ports (SDP), Charging Smart Power Selector Downstream Ports (CDP), and Dedicated Charger Ports Fully Compliant with Dead Battery/Weak Battery (DCP). The devices also detect common proprietary Charging According to USB 2.0 Specification charge adapters, including those from Apple. JEITA Charge Protection The MAX14746/MAX14747 battery chargers feature Thermal Protection Smart Power Selector operation, allowing operation with Internal USB D+/D- Switch to Manage Connection dead or no battery present. The devices limit USB V BUS Integrates High Level of Protection current based on the detect charger source type. If the 28V Tolerant Input on VB charger power source is unable to supply the entire system 15kV Human Body Model ESD Protection on load, the smart-power control circuit supplements the CDP and CDN system load with current from the battery. The devices protect against overvoltage faults up to 28V. This series of USB charger detectors are available with Ordering Information appears at end of data sheet. several options, with slight variations in, for example, power-up states. These variations are noted throughout this data sheet. There are five options available, with slight variations in, for example, power-up states (see Ordering Information). The devices are available in a 25-ball, 0.4mm pitch wafer- level package (WLP), and are specified over the -40C to +85C extended temperature range.
