The MAX6734KASVD2 is a part of the MAXIM family of supervisory circuits that provides a reset function for protecting microprocessors. As a supervisor IC, MAX6734KASVD2 provides a variety of features that are essential for ensuring reliable system operation, such as reset threshold accuracy, pushbutton reset control, and active-low reset pulse width control.

Application Field

The MAX6734KASVD2 supervisor IC is used in many applications as a reset and monitoring chip. It can be used for detecting and monitoring various input levels, providing reset signals for microprocessors and digital logic systems, or for providing a manual reset on demand. In addition, it can also be used for monitoring multiple supply rails and providing reset status of the system. The MAX6734KASVD2 is used in a wide variety of electronic products, including computers and embedded systems, data-logging systems, automotive applications, and network equipment.

Working Principle

The MAX6734KASVD2 supervisor IC contains four independent monitor circuits and three reset outputs. Each of the four monitor circuits consists of a voltage threshold detector with a preset threshold, an optional watchdog timer, and a power-on reset (POR) circuit. The preset thresholds can be manually programmed by the user. When the voltage level at any one of the monitor inputs exceeds the preset threshold, the corresponding monitor output goes active. The monitor circuits can be used to detect and monitor various voltage levels such as power-on, power-off, and supply rails.

The MAX6734KASVD2 also has an internal reset source with a reset pulse width control circuit. The reset pulse width control circuit adjusts the reset pulse width according to the selected reset delay time. When any of the four monitor circuits is active, a reset signal is issued at the RESET and POWER_ON pins. In addition, the MAX6734KASVD2 also has a manual reset input, MR, which can be used to issue a manual reset.

The MAX6734KASVD2 supervisor IC is a reliable and cost effective solution for reset and monitoring microprocessor and digital logic systems. It can be used to detect and monitor a variety of input levels, provide reset and power-on signals, and provide manual reset on demand. It is widely used in computers and embedded systems, datalogging systems, automotive applications, and network equipment.
