Introduction

Maxim Integrated\'s MAX8596ZETA+T is a high performance PMIC, or power management IC, that can provide up to four LED drivers. It is a highly integrated LED driver solution that allows LED display backlight control and shut off in various application fields. It also provides wide-range dimming control and dimming curve control, providing accurate performance as well as power saving capabilities. MAX8596ZETA+T comes with a tiny 0.25µm to save valuable board space for the application.

Application Field

MAX8596ZETA+T is most commonly used in LED display backlight control and shut off in portable consumer products, such as portable PCs, digital still cameras, camcorders, navigation systems, and liquid crystal displays. Other applications include lighting lamps and diodes for automotive, medical, industrial, and test equipment. With its wide range dimming control and dimming curve control, it is also ideal for industrial design, automotive illumination, aircraft cockpit illumination, and building lighting control.

Working Principle

MAX8596ZETA+T can provide up to four LED drivers – three common-anode PWM+LED drivers and one dimConfig™ dimming driver. The LED drivers control LED LED brightness with a wide range of dimming resolutions. Generally, programmable pulse rise/fall times are used to control LED LED brightness. The peak current of each output can be digitally adjusted with 0~255 steps for the LED\'s dimming range and power saving.

The MAX8596ZETA+T also integrates 0.25µm advanced analog and digital controllers that include power-on reset, watchdog timer, standby-current optimization, and low-power shutdown modes. It also provides comprehensive over-current protection, short-circuit protection, and circuitry that prevents reverse flows in the LEDs. It is also equipped with input-output pins that can be multiplexed by software.

Conclusion

MAX8596ZETA+T is a versatile and highly integrated PMIC or power management IC designed for LED display backlight control and shut off in various application fields. It comes with up to four LED drivers for wide range dimming control and dimming curve control. It also provides power saving features with a 0.25µm SIM chips and together with input-output pins that are programmable. MAX8596ZETA+T is suitable for a variety of applications, including portable consumer products, lighting lamps and diodes for automotive, medical, industrial and test equipment, and more.
