MAX77961EFV06+

Overview

The MAX77961EFV06+ is a USB Type-C Power Delivery Buck-Boost charger designed for single-cell lithium-ion or lithium-polymer batteries. It supports input voltages up to 25V and delivers a programmable constant charging current of up to 6A. The device integrates a smart power selector for seamless system power path management, enabling immediate system startup during charging. Key electrical features include a 600kHz switching frequency, remote differential voltage sensing, and an adaptive input current limit with input voltage regulation.

Feature Summary

• Integrates a buck-boost converter topology capable of handling wide input voltage ranges while supporting USB Type-C PD applications.
• Features a smart power selector that manages the system power path to allow instant system startup even when the battery is depleted.
• Includes built-in thermal regulation via a thermal foldback circuit and a charge safety timer to ensure operational reliability.
• Supports JEITA-compliant NTC thermistor monitoring for precise temperature management during the charging process.

Applications

• USB Type-C powered devices requiring wide input voltage compatibility
• Smartphones and tablets utilizing single-cell battery architectures
• Two-in-one laptops and handheld computing terminals
• Medical equipment and health monitoring wearables
• Digital cameras, camcorders, and drone systems

Procurement Notes

Verify the specific suffix EFV06 against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the part number with Analog Devices documentation to validate availability status, as supply constraints may affect procurement timelines.

Selection Notes

Select this component for designs requiring high-efficiency charging in space-constrained portable electronics. The integrated power path eliminates the need for external power path controllers. Consider the 30-pin FC2QFN package dimensions for PCB layout constraints. Verify that the application's input source can support the required peak currents for the selected charging profile.

Part Context

This part belongs to the MAX77960/MAX77961 family of buck-boost chargers from Analog Devices (formerly Maxim Integrated). The MAX77961 variant is distinguished by its higher maximum output current capability compared to the MAX77960. Both share similar control interfaces and protection features, targeting modern mobile and industrial handheld devices.

Replacement Considerations

The MAX77960BEVKIT evaluation board is associated with the MAX77960 variant. Designers should verify pin-to-pin compatibility and current rating differences if substituting between MAX77960 and MAX77961 models. No other direct substitutes are confirmed in the provided data.
