产品详情

The MAX14746/MAX14747 are a series of USB charger detectors with an integrated Smart Power Selector™ linear charger solutions that provide a single-chip solution for charging and charger detection.

The MAX14746/MAX14747 charger detectors are compliant to USB Battery Charger Detection Rev 1.2* and capable of detecting multiple USB battery-charging methods, including Standard Downstream Ports (SDP), Charging Downstream Ports (CDP), and Dedicated Charger Ports (DCP). The devices also detect common proprietary charge adapters, including those from Apple.

The MAX14746/MAX14747 battery chargers feature Smart Power Selector operation, allowing operation with dead or no battery present. The devices limits USB VBUS current based on the detect charger source type. If the charger power source is unable to supply the entire system load, the smart-power control circuit supplements the 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 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. The devices are available in a 25-ball, 0.4mm pitch wafer-level package (WLP), and are specified over the -40°C to +85°C extended temperature range.
