MAX8784ETL+

MAX8784ETL+ is a power management integrated circuit (PMIC) specifically designed for commercial and industrial applications. It can provide up to 6A of continuous current with a voltage range of 2.5V to 5.5V. The device consists of a 6-channel step-down DC/DC converter, a dedicated low voltage system power regulator, and an interval timer with Optional RTC. It is a low cost, low power, low complexity integrated circuit solution that addresses space, cost, and power optimization in a wide range of applications.

The MAX8784ETL+ family of products is specifically designed to reduce overall system bill of materials (BOM) and PCB size while providing cost savings in the form of fewer components, reduced assembly time, and enhanced reliability. It features built-in power-on reset and power-up sequencing; reverse blocking MOSFETs; and an optional temperature-controlled charging current. The device also provides an external power supply for supply current or for hot-swap applications. The device has two modes of operation: low voltage system power regulation, and step-down DC/DC conversion.

The low voltage system power regulator is a precision, high power, and low quiescent current system power regulator. It operates in either fixed or adjustable mode, with adjustable outputs available as low as 0.8V. The device features low power shutdown, programmable overcurrent protection and short-circuit protection. It is designed to eliminate generator power sequencing problems associated with automatic voltage scaling, and provides fast-transient response for rapid load regulation.

The MAX8784ETL+ step-down DC/DC converter provides high efficiency and low output noise for compact SMPS designs. It operates from an input voltage of 2.75V to 5.5V and has an adjustable output voltage from 0.8V to 5.5V. The device offers up to 95% efficiency, low noise operation, and a 0.2μA (typ) quiescent current. It also features adjustable switching frequency, programmable soft-start, adjustable output current limit and adjustable output voltage.

The MAX8784ETL+ interval timer with optional RTC is a 6-pin timer specifically designed for cost-sensitive timing applications. It offers a range of features and functions, including 8-bit interval timers, 8-bit real-time clock, flexible output configurations, and an optional interrupt output with programmable time-out mode. The device is designed to be used in a wide range of applications, such as appliance and automotive, medical, building control and security systems.

The MAX8784ETL+ is a highly integrated PMIC solution that offers a range of features and functions to meet the requirements of various commercial and industrial applications. It has low power consumption and a small form factor; 6-channel step-down DC/DC converter, dedicated low voltage system power regulator, and optional RTC timer; as well as programmable overcurrent protection and short-circuit protection for added reliability. Furthermore, it provides excellent efficiency, and fast transient response for rapid load regulation. All these features make the MAX8784ETL+ ideal for applications where space and cost are of prime concern.
