APM8601FB-7

Overview

The APM8601FB-7 is a dual-channel battery charger IC from Diodes Incorporated, designed for lithium-ion and lithium-polymer batteries. It features 28V overvoltage protection and automatic input selection between USB and DC sources. The device supports a maximum fast charge current of 1A, with USB input currents configurable to 100mA or 500mA via logic levels. It implements standard charging algorithms including pre-charge, constant current, and constant voltage phases. The IC operates within a supply voltage range up to 7V and functions across an extended temperature range of -40°C to +85°C.

Feature Summary

• Dual-channel architecture for independent battery management
• Automatic source selection between USB and DC inputs
• Comprehensive safety monitoring for overvoltage, overtemperature, and timeout conditions
• Programmable charging parameters via external resistors and capacitors

Applications

• Mobile phones
• Media players
• Wireless headphones

Procurement Notes

Verify component status as the APM8601FB-7 is listed as obsolete by the manufacturer. Confirm availability through authorized distributors or secondary market channels. Ensure that any replacement components maintain compatibility with existing circuit designs and thermal requirements. Check for updated datasheets to confirm pinout and electrical specifications before integration.

Selection Notes

Select this component for applications requiring dual-cell charging capabilities with robust input flexibility. The automatic detection of USB versus DC power simplifies system design by removing manual switching logic. Consider the programmable nature of the charging profile to tailor performance to specific battery chemistries and capacity requirements while ensuring compliance with safety standards.

Part Context

This part belongs to the APM860x series of battery chargers from Diodes Incorporated. The series includes single-channel variants like the APM8600, which lacks the automatic input selection feature found in the dual-channel APM8601. These devices are engineered to provide safe and efficient charging solutions for portable electronics, emphasizing reliability and compact form factors suitable for modern consumer devices.

Replacement Considerations
