ADP8860ACBZ-R7

Overview

The ADP8860ACBZ-R7 is a charge pump-based smart LED driver IC manufactured by Analog Devices Inc. It features seven independent output channels, each capable of delivering up to 60 mA. The device operates on an input voltage range of 2.5 V to 5.5 V and utilizes a 1 MHz switching frequency. It is housed in a WLCSP-20 package and supports I2C control interface for configuration. The component functions as a DC-DC regulator with internal switches, designed for efficient backlight control applications.

Feature Summary

• Integrates seven independent current-regulated output channels for multi-segment LED driving
• Utilizes charge pump topology to boost input voltage for LED string operation
• Enables digital configuration and monitoring via standard I2C serial interface
• Includes internal protection mechanisms for safe LED operation

Applications

• LCD panel backlight systems
• Multi-segment indicator lighting
• Portable electronic device illumination

Procurement Notes

Verify the specific suffix ACBZ-R7 to confirm the WLCSP-20 package type and reel packaging format. Ensure compatibility with I2C bus voltage levels and check for RoHS compliance documentation prior to integration. Confirm availability status as supply conditions may vary by region.

Selection Notes

Select this component when a compact solution for driving multiple LED strings from a single low-voltage source is required. The WLCSP-20 package offers space efficiency for dense PCB layouts. Consider the 60 mA per channel limit and the 1 MHz switching frequency when designing thermal management and EMI filtering strategies.

Part Context

This part belongs to the ADP8860 series of smart LED drivers. It shares functional similarities with the ADP8861 but differs in packaging, utilizing a wafer-level chip-scale package instead of LFCSP. The series is designed for high-efficiency backlighting in mobile and portable electronics.

Replacement Considerations

The ADP8860ACPZ-R7 is a pin-compatible alternative using an LFCSP-20 package. Verify package dimensions and thermal characteristics before substitution. No other direct substitutes are confirmed in public documentation.
