Applications
MAX6964ATG+T is used in industrial HMI panels, network switch front plates, and server status boards where 17 independently dimmable LED indicators must be controlled over a 2-wire I2C bus from a host processor. It is also employed in consumer electronics keypads, medical device front panels, and telecom equipment where hot-insertion protection allows the LED board to be swapped without powering down the host system.

Frequently Asked Questions
How many LED outputs does the MAX6964ATG+T provide and can each be independently dimmed?
The MAX6964ATG+T provides 17 output channels, each independently configurable as an LED driver with per-channel intensity control through I2C register writes, or as a general-purpose output. This lets designers drive 17 status LEDs at different brightness levels from a single 24-pin device without external PWM logic.
What interface does MAX6964ATG+T use and how many devices can share the same bus?
The device communicates over a 2-wire I2C serial interface, which allows multiple MAX6964ATG+T units to share the same SCL and SDA lines using distinct I2C addresses. This is useful for indicator panels requiring more than 17 outputs, where 2 or 3 devices can drive up to 51 LEDs using only 2 microcontroller pins.
What does hot-insertion protection mean for MAX6964ATG+T in live-swap system designs?
Hot-insertion protection means the device tolerates its VCC and I/O pins being connected while the host board is powered, without causing latch-up or drawing excessive current. This allows the LED driver board to be physically inserted or removed in field-replaceable unit designs without shutting down the host system or risking damage to the 24-pin QFN device.
How does the QFN-24 package size of MAX6964ATG+T support high-density LED panel designs?
The 24-LFCSP package body is 4 mm x 4 mm x 0.75 mm with a 0.5 mm pin pitch and exposed thermal pad, fitting 17 LED driver channels within a footprint smaller than many 16-pin SOIC devices. This high integration ratio reduces PCB area compared to using discrete transistor arrays or multiple smaller driver ICs to achieve the same 17-output count.
