MAX6977AAE+

LED Driver IC Overview

The MAX6977AAE+ is an 8-port constant-current LED driver IC from the Maxim Integrated family, manufactured by Analog Devices Inc. It operates on a logic supply voltage ranging from 3 V to 5.5 V and provides a regulated output current of 55 mA per channel. The device utilizes a boost topology to drive LEDs and features open-circuit fault detection for each port. It is housed in a 16-lead SSOP package and supports serial interface control for brightness and configuration.

LED Driver IC Feature Summary

• Provides eight independent constant-current outputs with programmable brightness levels
• Integrates open-circuit fault detection for individual LED ports
• Utilizes a boost converter topology to drive high-voltage LED strings from low-voltage supplies
• Supports serial interface communication for simplified system integration

LED Driver IC Applications

• Portable electronic displays requiring compact LED driving solutions
• Backlighting systems for mobile devices and handheld instruments
• General-purpose indicator lighting in consumer electronics
• Embedded systems with limited power supply headroom

LED Driver IC Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific suffix variations against official datasheets. Check for obsolescence notices or lifecycle changes prior to procurement. Ensure packaging specifications match design requirements for surface-mount assembly processes.

LED Driver IC Selection Notes

Select this component when an 8-channel solution with integrated boost capability is required. Compare against alternative drivers based on pin count, thermal performance, and interface compatibility. Evaluate total system cost including external passive components needed for the boost circuit. Consider operating temperature range and package size constraints for the target application enclosure.

LED Driver IC Part Context

This part belongs to the MAX6977 series of LED drivers designed for portable applications. It complements other Maxim Integrated display drivers by offering integrated power management features. The series targets designers needing to reduce bill-of-materials count by combining driver logic with power conversion stages in a single package.

LED Driver IC Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify functional equivalence with other 8-port LED drivers only after consulting official cross-reference lists from Analog Devices.
