ADP8863ACPZ-R7

Overview

The ADP8863ACPZ-R7 is a charge pump-based backlight controller and LED driver IC manufactured by Analog Devices. It features seven independent output channels capable of driving up to 60 mA per channel, with an input voltage range of 2.5 V to 5.5 V and a switching frequency of 1 MHz. The device operates within a temperature range of -40°C to +85°C and is housed in a 20-pin LFCSP package. Control is managed via an I2C interface, supporting configurable fade times, blink functions, and ambient light sensing zones for optimized power savings.

Feature Summary

• Integrates seven individually programmable LED output channels with adjustable brightness levels.
• Supports three distinct ambient light sensing zones for dynamic backlight power management.
• Features software-configurable fade-on/off times and blink functions for smooth visual transitions.
• Utilizes an I2C serial interface for comprehensive control and status monitoring.

Applications

• Backlight LED Linux drivers
• Mobile phone displays
• Digital still cameras (DSC)
• Portable media players

Procurement Notes

Verify the specific suffix R7 indicates tape-and-reel packaging when sourcing. Confirm the ACPZ variant corresponds to the LFCSP-20 package type. Ensure compatibility with the intended I2C bus speed and logic levels. Check for RoHS compliance documentation if required by your manufacturing standards. Validate that the operating temperature range meets your environmental specifications.

Selection Notes

Select this component when multiple LED strings require individual current control within a compact form factor. The integrated charge pump eliminates the need for external inductors, simplifying PCB layout. Consider the I2C addressability if multiple devices share the same bus. Evaluate the ambient light sensor integration against discrete sensor requirements for system cost reduction.

Part Context

This part belongs to the ADP886x series of backlight controllers designed for portable electronics. It shares functional similarities with the ADP8860 and ADP8861 but includes additional ambient light sensing capabilities not present in all family members. The series targets applications requiring high efficiency and precise brightness control in space-constrained designs.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout and electrical parameters carefully if considering alternative LED drivers from other manufacturers.
