LED Driver IC Procurement Notes

Verify the product status carefully before procurement, as this specific part number is listed as obsolete or scheduled for discontinuation by the manufacturer. Availability may be limited to existing stock or special factory orders. Confirm that the PDIP-16 through-hole package meets your PCB design requirements. Ensure compatibility with the 3 V to 5.5 V supply voltage range for your target application environment.

LED Driver IC Selection Notes

Select this component when an 8-channel constant-current solution with fault detection is required. It is suitable for designs needing a shift register interface and boost topology. Consider the PDIP-16 package constraints for through-hole assembly. Verify that the 55 mA per channel output aligns with the LED specifications. Evaluate the operating temperature range of -40°C to +125°C against environmental conditions.

LED Driver IC Part Context

This device belongs to the MAX6977 series of LED drivers from Maxim Integrated, now part of Analog Devices. It is distinct from other supervisory circuits in the broader MAX697 family, such as the MAX697MJE/883B. The MAX6977APE specifically targets multi-channel LED illumination tasks rather than system monitoring or reset generation functions.

LED Driver IC Replacement Considerations

As the part is obsolete, identify equivalent 8-port LED drivers with similar boost topology and constant current characteristics. Verify pinout compatibility with the 16-PDIP package if direct replacement is desired. Check for updated versions within the same product family that may offer enhanced features or availability.
