MAX16823ATE+

PMIC - LED Drivers

The MAX16823ATE+ is an LED driver that is powered by PMIC (Power Management Integrated Circuits). This LED driver is suitable for driving a small array of multiple low-side LEDs and provides flexibility with the capability for manual (M) or PWM (S) control modes and can be externally synchronized to other drivers.

Application Field

The MAX16823ATE+ LED driver can be used in a variety of applications including automotive lighting and high output solid-state luminaires. It has the ability to be used in applications where a manual or PWM dimming function is desired and it is well-suited for automotive interior lighting, rear and warning lights, backlighting, and digital displays and signage.

Working Principle

The MAX16823ATE+ LED driver works on the principle of thermal management. When the LED driver is enabled, the current is lowered to maintain a system temperature within the permissible maximum range. The MAX16823ATE+ LED driver monitors the temperature using an internal thermal sensing circuit and adjusts the output current accordingly. This keeps the LED and LED driver within the operational limits and produces less noise and a more consistent light output.

The MAX16823ATE+ LED driver is designed to have a wide input voltage range to meet the requirements of different applications and the output current can be adjusted through an external resistor. Output currents are designed to be in the range of 92mA to 500mA in manual control mode but can reach up to 600mA in PWM control mode. It can also be synchronized to other drivers and then control multiple arrays of LEDs from one channel.

In addition, the MAX16823ATE+ offers two adjustable current settings with a configurable dimming, allowing for a range of custom lighting effects. It also features protection features, such as a soft start circuit, short-circuit protection, over-temperature protection, and short-circuit hysteresis. This makes it an ideal choice for applications that demand reliability and safety.

Conclusion

The MAX16823ATE+ is a reliable, efficient, and cost-effective PMIC-powered LED driver. Its ability to be used in different applications, wide operating voltage range, adjustable current settings, and several protection features make it an ideal choice for driving small array multiple low-side LEDs.
