Introduction

The MAX16003DTE+ is a highly integrated bi-directional voltage-mode control supervisor designed to supervise power converter circuits. It features bi-directional controlled-on/off control and maximizes efficiency by monitoring the input supply and ensuring safe and secure start-up of powered circuits. In addition, the MAX16003DTE+ offers a variety of operating modes, wide range of input voltage, and better power-on reset control for improved safety and reliability.

Key Features and Benefits

The MAX16003DTE+ provides power-on reset (POR), power-on off (POO), open-drain output, adjustable-stalled-speed fan control, and adjustable-duty cycle noise removal features. It also features a dual-ground-referenced source to provide bi-directional level shifting between the input power source and the power converter. A wide range of microcontroller-friendly features further simplifies down-stream circuits.

Application Field

The MAX16003DTE+ is ideal for use in applications where safety and reliability are paramount, such as in medical, avionics, robotics, industrial, and automotive systems. Furthermore, its capability for bi-directional voltage-mode control makes it a great fit for power-converter applications such as multi-output DC/DC converters, inverters, and battery chargers.

Working Principle

The MAX16003DTE+ supervises the supply and converter circuits by enabling or disabling them through an open-drain output. This output can be controlled through an I 2 C/SMBus™ slave interface or via a logic signal from the power-converter analog stage. The MAX16003DTE+ monitors the input voltage to protect the system from inadequate and/or over-voltage conditions. It responds by disabling its output in accordance to user settings. Additionally, the MAX16003DTE+ monitors the device’s temperature to provide thermal protection of the converters and other downstream circuits. The MAX16003DTE+ also features adjustable-stalled-speed fan control that can be used to control the speed of a fan. In addition, the device features adjustable-duty cycle noise removal to reduce emissions and reduce EMI susceptibility.

Conclusion

The MAX16003DTE+ provides an efficient, safe, and reliable way to supervise power converter circuits in a wide range of applications. Its bi-directional voltage-mode control enables quick and secure start-up of powered circuits, while adjustable-stalled-speed fan control and adjustable-duty cycle noise removal reduce emissions and ensure compliant operation. Furthermore, its microcontroller-friendly features simplify downstream circuits to make design and implementation easier.
