MAX6967ATE+T

LED Driver IC Overview

The MAX6967ATE+T is a 10-port constant-current LED driver and I/O expander featuring PWM intensity control. It operates on a supply voltage of 2.25 V to 3.6 V with a maximum power dissipation of 1.176 W. The device provides a low-level output current of 21.1 mA per channel and draws a maximum supply current of 730 uA. It supports an operating temperature range from -40°C to +125°C and is housed in a 16-TQFN package.

LED Driver IC Feature Summary

• Integrates ten constant-current LED driver ports with independent pulse-width modulation intensity control for precise brightness adjustment.
• Functions as a general-purpose input/output expander, allowing flexible configuration of digital signals alongside display driving capabilities.
• Utilizes a serial interface compatible with standard SPI protocols to minimize microcontroller pin usage and simplify system wiring.

LED Driver IC Applications

• Portable electronic devices requiring compact LED status indicators
• Consumer appliances with multi-segment display requirements
• Industrial control panels needing integrated I/O expansion

LED Driver IC Procurement Notes

Verify the specific suffix 'ATE' against the manufacturer's official documentation to confirm the exact temperature grade and tape-and-reel packaging specifications. Ensure compatibility with the target PCB footprint for the 16-TQFN package. Cross-reference the RoHS compliance status with the latest datasheet revision to meet environmental regulations. Confirm that the 3.6 V maximum supply voltage aligns with the system power design constraints.

LED Driver IC Selection Notes

Select this component when a design requires both high-density LED driving and additional digital I/O lines within a limited pin count. The low supply current makes it suitable for battery-operated applications where power efficiency is critical. Verify that the required LED forward voltage does not exceed the device's output voltage limits. Consider the thermal performance in the 16-TQFN package if multiple channels are driven at maximum current simultaneously.

LED Driver IC Part Context

This part belongs to the Maxim Integrated line of display drivers designed for space-constrained applications. It combines display functionality with logic expansion to reduce overall system component count. The series is known for integrating constant-current sources directly onto the silicon, eliminating the need for external current-limiting resistors in many configurations.

LED Driver IC Replacement Considerations

Consult the official Analog Devices cross-reference guide for verified substitutes. Ensure any replacement maintains the 16-TQFN footprint or includes a compatible pin-to-pin alternative. Verify that the substitute supports the same 2.25 V to 3.6 V operating range and offers equivalent port counts.
