ACT2861QI401-T

Overview

The ACT2861QI401-T is a battery management integrated circuit designed for charging applications involving two to five series-connected lithium-ion or lithium-polymer batteries. It operates as a Buck-Boost charger with an input voltage range of 3.9 V to 29 V and supports output currents up to 5 A. The device integrates four power MOSFETs and includes On-The-Go (OTG) functionality, allowing it to function as a boost converter for external load powering. It utilizes a FCQFN-42 package suitable for surface mount installation.

Feature Summary

• Integrates four internal MOSFETs to minimize external component count and reduce solution size.
• Supports bidirectional power flow through integrated OTG capability for simultaneous charging and discharging operations.
• Optimized for low quiescent current in transport, shutdown, and standby modes to preserve battery life.

Applications

• Portable electronic devices requiring multi-cell battery charging
• Power banks with dual-port capabilities
• Industrial handheld equipment

Procurement Notes

Verify the specific suffix against official Qorvo documentation to confirm pinout compatibility and electrical tolerances. Confirm availability status directly with authorized distributors as supply chain conditions vary. Ensure the ordering part number matches the required thermal and packaging specifications for the target application.

Selection Notes

Select this component when designing systems that require wide input voltage flexibility and high current handling for multi-cell configurations. The integrated MOSFET architecture simplifies PCB layout compared to discrete solutions. Evaluate thermal performance requirements based on the FCQFN-42 package constraints during the design phase.

Part Context

This part belongs to the ACT2861 family of charge management ICs from Qorvo. The family focuses on providing compact, efficient solutions for portable electronics. The ACT2861 series distinguishes itself by combining buck-boost topology with OTG features in a single chip, reducing the bill of materials for complex power management needs.

Replacement Considerations

ACT2861QI201-T is listed as a potential substitute within the same product family. Verify functional equivalence and pin compatibility before implementation.
