The MAX8630XETD20+T is an LED driver PMIC device with a wide operating temperature range of up to -40°C to +125°C, making it ideal for applications in harsh environment applications. This device is suitable for industrial, automotive, and other markets, with high-power LED lighting solutions. It features a fast soft-start for improved system safety. This device is also a fast analog dimming controller capable of PWM brightness control from a low of 0.1% up to full brightness.

This device operates using I2C compatible protocol and provides a vast array of lighting control options. It can be configured and managed easily through register-level programming. Buttons, rotary dimmers, or circuit-level dimming controllers can be used to control the brightness of the LEDs. It also supports adjustable flicker-free dimming down to 1%, and a wide range of external dimming control options.

The MAX8630XETD20+T uses powerful digital dimming techniques from Analog Devices and is capable of delivering maximum current up to 10 times greater than a standard LED driver running at 600% overdrive current. This current can be controlled from 0mA to 0.2mV in digital resolution, allowing for efficient LED current control. It has a digital LED diagnostic feedback voltage accuracy of up to ±4mV, letting users diagnose LED-related power losses, including LED damage and wear. A constant current accuracy of ±1% helps ensure consistent LED lighting.

This device also supports automatic current adaption and temperature sensing, allowing it to automatically adjust the LED current more closely to maintain desired brightness in the event of hot environments or continuous bright operating conditions. Additionally, the MAX8630XETD20+T supports open circuit protection to protectit against steep voltage spikes, reverse voltage and over temperature conditions.

The MAX8630XETD20+T LED driver is a highly integrated controller that is capable of providing advanced current control, dimming control, diagnostics, and protection features for LED lighting applications. Its high efficiency, wide temperature operating range, advanced digital dimming capabilities, and comprehensive protection make it well suited for industrial, automotive, and other harsh environment applications.
