ADP8860ACPZ-R7

Overview

The ADP8860ACPZ-R7 is a charge pump-based LED backlight controller manufactured by Analog Devices Inc. It features seven independent output channels, each capable of delivering up to 60 mA. The device operates within an input voltage range of 2.5 V to 5.5 V and supports I2C control for configuration. It utilizes a 1 MHz switching frequency and is housed in a 20-lead LFCSP package. The component functions with supply voltages between 4.3 V and 5.5 V and is rated for operation from -40°C to +85°C.

Feature Summary

• Integrates seven independent current-regulated outputs for multi-zone LED driving
• Utilizes charge pump topology to boost input voltage for LED string powering
• Enables digital configuration and monitoring via standard I2C interface

Applications

• Mobile phone LCD backlight systems
• Portable electronic device display illumination
• Multi-segment LED lighting arrays

Procurement Notes

Verify the specific suffix R7 indicates reel packaging when sourcing. Confirm the LFCSP-20 package variant matches your PCB footprint requirements. Ensure the I2C address settings align with your system bus constraints. Check for moisture sensitivity level compliance during storage and handling procedures.

Selection Notes

Select this component when designing systems requiring multiple independently controlled LED zones from a single driver IC. It is suitable for applications where space is limited due to its compact LFCSP-20 form factor. Consider the 60 mA per channel limit to ensure adequate brightness without exceeding thermal or electrical ratings.

Part Context

This part belongs to the ADP8860 series of LED drivers designed for portable electronics. It serves as a specialized solution for managing complex backlighting needs in mobile devices. The series focuses on providing high integration and precise current regulation for display applications.

Replacement Considerations

Consult official Analog Devices documentation for verified cross-reference part numbers. Do not assume functional compatibility with other LED drivers without verifying pinout and electrical specifications.
