MAX8677AETG+ Description

Short technical summary and product information.

The MAX8677AETG+ is a versatile integrated circuit designed for charging 1-cell Lithium-Ion batteries. It functions as both a charger and a Smart Power Selector, featuring dual power inputs for DC and USB sources. This allows for flexible power management, enabling the system to operate even with a discharged or absent battery.

 

The device integrates all necessary power switches, eliminating the need for external MOSFETs. Key electrical specifications include a programmable charge current up to 1.5A and an input current limit up to 2A. The USB input current can be set to 100mA or 500mA. It provides a typical SYS regulation voltage of 5.3V and includes input overvoltage protection up to 16V. The system-to-battery switch has a low resistance of 40mΩ.

 

Additional features enhance its utility in portable applications. These include automatic input selection between battery, USB, and adapter power, support for load peaks exceeding adapter ratings via battery, and on-chip thermal limiting to prevent overheating. The MAX8677AETG+ also offers charge status and fault outputs, power-OK monitors, a charge timer, and a battery thermistor monitor.

 

Packaged in a compact 4mm x 4mm, 24-pin TQFN-EP package, the MAX8677AETG+ is suitable for surface mount applications. Its operating temperature range is -40°C to 85°C.
