ADIMAX14748
Overview
The MAX14748 is a highly integrated USB Type-C charger solution designed for 2-cell Lithium-ion battery packs. It combines a smart power selector, a high-efficiency DC-DC converter with boost and reverse-buck capability, and comprehensive USB detection logic in a compact 54-WLP package. The IC supports USB Type-C Rev 1.1 with UFP/DRP operation and includes 28V overvoltage protection on the input.
Why Choose This Part
The IC simplifies design by integrating a Super-Speed multiplexer logic control and internal USB switches for data lines, reducing PCB footprint. It features Automatic Input Current Limit (AICL) to prevent crashing weak power sources and provides 15kV ESD protection on USB adapter pins. The 2-cell support with an 8.3V pack voltage and smart power selection allows the system to operate even with a dead or missing battery.
Applications
Key Specifications
Getting Started
Evaluation can be performed using the MAX14748EVKIT, which provides a complete hardware environment to exercise the I2C registers and power paths. Designers should refer to the datasheet for thermal layout guidelines regarding the 54-WLP package to manage the 2A maximum charge current. Integration requires an I2C host to configure charge parameters and monitor the thermistor and status flags.
