The MAX1916EZT+T is a low-dropout, constant-current triple white LED bias supply from Analog Devices, designed as a high-performance alternative to simple ballast resistors. It uses a single resistor to set the bias current for three LEDs, achieving 0.3% LED-to-LED current matching.
This linear LED driver operates over a supply voltage range of 2.5V to 5.5V and provides up to 60mA of bias current per LED. It features a low dropout voltage of 200mV at a 9mA load, ensuring efficient operation. The device consumes only 40µA of supply current when enabled and a mere 0.05µA when disabled, making it suitable for battery-powered applications.
Key advantages over ballast resistors include significantly better LED-to-LED bias matching, lower bias variation with supply voltage, and improved efficiency in certain applications. The MAX1916EZT+T includes thermal shutdown protection for added reliability.
Packaged in a space-saving 6-pin Thin SOT-23 (TSOT-23-6) package, this LED driver is ideal for applications such as next-generation wireless handsets, PDAs, digital cameras, and other battery-powered equipment requiring precise LED brightness control.
