From wireless microphones to high-end cameras, VR headsets and even motorized medical devices, the USB Type-C connector provides an easy solution for charging and streaming multimedia data in a variety of applications, often powered by 2-cell tandem battery, which also requires Recharging to provide sufficient power So far, developing USB Type-C products powered by 2-series battery packs requires multiple external discrete components that not only add to bill of materials (BOM) costs and introduce additional faults in the circuit point.
The MAX14748 integrates a charger, USB Type-C charger detection, 28V overvoltage protection and power supply circuitry in a single chip to dramatically simplify design. The highly integrated solution is compatible with traditional USB BC1.2 charging and other non-standard charging requirements. USB Type-C Charges up to 2x the Micro USB Programmable Programmable Auto-Input Current-Limit (AICL) Maximizes Rechargeable Adapter Current While Protecting Your Safety Maximizes End-Of-Life Devices With the MAX14748, Maxim Will Continue Expands its power-supply-related product portfolio to meet unique USB Type-C application requirements.Currently available products include the MAX77756 24V input, 500mA buck regulator, the MAX17205 Standalone ModelGauge ™ m5 with SHA-256 safety certification, and MAX20323 CC Pin Overvoltage Protector.
Key Benefits • Reduced Power Management Sizing: Unlike traditional charging solutions, the MAX14748 integrates a charger detector, a buck-boost converter, a Li-Ion battery charger with an intelligent power selector in a single chip to minimize Discrete Components • Fast and Secure Charging: The MAX14748 charges a 2-cell series Li-Ion battery using a conventional 5V USB adapter with AICL features to prevent overshoot • Additional protection features available: MAX14748 28V integrated over USB adapter pin Voltage Protection, JEITA Charge Protection and ± 15kV Electrostatic Discharge Protection.
