Introduction

The MAX20078ATE/VY+ is a P-channel MOSFET driver that consists of a high-side, low-side switch and logic, optimized for use as a power management integrated circuit (PMIC) LED driver. It offers high performance and low power operation, making it ideal for applications requiring high efficiency in the presence of load transients and heavy loading conditions, such as those found in automotive LED lighting.

Application field

The MAX20078ATE/VY+ PMIC LED driver can be used in a wide range of automotive LED applications such as turn signals, brake lights, daytime running lights, tail lights, and fog lights. Additionally, it can be used for aftermarket automotive LED upgrades or applications in industrial or machine vision lighting, commercial lighting, and home lighting systems.

Working Principle

The MAX20078ATE/VY+ P-channel MOSFET driver consists of a high-side, low-side switch and logic, optimized for use as a PMIC LED driver. Its operation is based on an input voltage measurement (VIN) along with an external reference voltage (VREF), which determines the point of turn-on operations for both the high-side and low-side transistors of the driver. In this way, the driver provides high efficiency, low power operation, and extremely fast response times even under load transient conditions. The MAX20078ATE/VY+ utilizes a fail safe feature that will turn off the output when it senses an over voltage at the Controlled Node pin. This feature provides protection from potential over voltage conditions that could otherwise damage the LED and other components in the system.

Conclusion

The MAX20078ATE/VY+ PMIC LED driver is a high performance, low power MOSFET driver that offers fast response time and high efficiency, even under heavy load transient conditions. It is ideal for automotive LED applications such as turn signals, brake lights, daytime running lights, tail lights, and fog lights, as well as aftermarket automotive LED upgrades, industrial or machine vision lighting, commercial lighting, and home lighting systems. Additionally, the fail safe feature provides protection from potential over voltage conditions that could otherwise damage the LED and other components in the system.
