MAX6759UTTD0+T

The MAX6759UTTD0+T is a sophisticated integrated circuit designed specifically for use in the protection of system power on/off and reset operations in powered equipment. It is part of the PMIC (Power Management IC) family of products, categorized as Supervisors.

This device provides a high degree of monitoring, control and fault handling to ensure that a system is correctly powered in an orderly manner. The MAX6759UTTD0+T helps prevent unexpected and undesired system operation resulting from unexpected power-ups or faults in the power-supply system.

The MAX6759UTTD0+T can significantly reduce the complexity and cost of designing and implementing supervisor circuits. It includes four input power-on/off control pins, an open-drain reset output pin, a configurable reset and undervoltage lockout threshold, and logic and analog interfaces. The failure-detection characteristics of the part are also highly flexible, allowing the user to customize their system to their particular needs.

The application field of MAX6759UTTD0+T is extremely wide since it can provide reset and undervoltage protection for a multitude of circuit designs and applications. In addition to handling the primary power-on/off and reset functions, this part can also provide a wide range of additional protection functions. These include power-fail detection, brownout detection, glitch and surge protection, low voltage inhibit, negative edge reset, or supply sequencing.

The operating principle of the MAX6759UTTD0+T is to monitor the supply voltage via the Reset Input pin, and when the voltage is within a certain tolerance (controlled by the RESET UTR and RESET LTR registers), activate the open-drain reset output pin. This pin can then be used to control the reset lines of digital circuits, such as microprocessors and microcontrollers, assuring that they are reset correctly and safely. The reset function of the MAX6759UTTD0+T is further enhanced with the option of setting a high-voltage lockout threshold, as well as an adjustable reset propagation delay.

The MAX6759UTTD0+T has a wide range of input voltages, up to 10V, and supports reset and wakeup operations as low as ~2V. In addition, this part comes in a small and easy-to-use 3.3V SOIC package, with a maximum op-amp supply voltage of 13V.

With its flexibility, reliability, and performance ranges, the MAX6759UTTD0+T has a perfect place in the PMIC Supervisors offering, providing a powerful package of features all in a single device. It is an ideal choice for use in a variety of applications, with its user-adjustable monitoring, control, and reset capabilities.
