• Supports reverse buck mode for USB On-the-Go (OTG) accessory powering without external inductors
• Includes adaptive input current limiting and input voltage regulation for robust power source management
• Features remote differential voltage sensing and thermal foldback loop for precise temperature control

Applications

• USB Type-C powered wide-input charging applications
• Smartphones, tablets, and 2-in-1 laptops
• Medical devices and health/fitness monitors
• Drones and electric tools
• Wireless speakers and handheld radios

Procurement Notes

Verify the specific suffix 'EFV12+' against official Analog Devices documentation to confirm pinout and electrical specifications. Ensure compatibility with required I2C or resistor-programming configurations. Check for restricted availability status as supply conditions may vary. Confirm RoHS compliance and moisture sensitivity level requirements for your assembly process before procurement.

Selection Notes

Select this component for applications requiring high efficiency (up to 97%) and compact solution size. It is suitable for systems needing flexible battery configurations (1S, 2S, or 3S) and robust power path management. Consider the 6 A output capability and wide input range when designing for variable power sources like USB PD adapters.

Part Context

This part belongs to the MAX77960/MAX77961 family of buck-boost chargers. These ICs are designed for mobile computing and handheld devices, offering integrated battery charging and power path management. The family supports various battery chemistries and provides comprehensive protection features including charge safety timers and overcurrent protection.

Replacement Considerations

The MAX77960EFV06+ is a related variant within the same family, offering similar functionality but with a lower 3 A output current rating. Verify if the reduced current capacity meets your system's peak load requirements before substituting.
