MAX6967ATE+

LED Driver IC Overview

The MAX6967ATE+ is a linear LED driver IC manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features a high-speed 26MHz serial interface compatible with SPI, QSPI, and Microwire protocols. The device operates within a voltage range of 2.25V to 3.6V and provides a constant output current of 20mA per channel. It utilizes a 16-TQFN package measuring 3x3 mm. Key electrical characteristics include an operating temperature range of -40°C to +125°C and an output voltage of 7V. I/O ports default to high-impedance on power-up.

LED Driver IC Procurement Notes

Verify component authenticity through authorized Analog Devices channels. Confirm package integrity and pin alignment against the 16-TQFN specification. Ensure supply chain documentation matches the MAX6967ATE+ designation. Check for RoHS compliance status prior to integration. Validate thermal performance within the specified operating temperature range during system testing.

LED Driver IC Selection Notes

Select this component for designs requiring precise LED current regulation at low supply voltages. The 2.25V to 3.6V operating range suits battery-powered applications. Consider the 20mA output capability for standard indicator or segment lighting. Evaluate the 16-TQFN footprint for space-constrained PCB layouts. Ensure the host controller supports the required 26MHz serial protocol timing.

LED Driver IC Part Context

This part belongs to the Maxim Integrated LED driver family, now part of Analog Devices. It complements other display drivers like the MAX6957 and MAX6968 by offering specific serial interface compatibility and lower voltage operation. The series focuses on simplifying MCU interfacing for portable consumer electronics and industrial displays.

LED Driver IC Replacement Considerations

Check for direct pin-compatible alternatives within the MAX6967 series variants. Verify if MAX6967AETG+ offers equivalent electrical specifications. Confirm that any substitute maintains the 26MHz serial interface speed and 20mA current rating. Ensure the replacement package matches the 16-TQFN form factor.
