The MAX6758UTTD0+T is a microprocessor supervisory circuit designed to monitor and maintain the steady state operation of microprocessor-based systems. This device provides reset output and voltage monitor functions, both of which are important in ensuring the operation of microprocessor-based systems. It is ideal for use in automotive applications, areas that require high reliability, or power systems incorporating costly components.

The MAX6758UTTD0+T Supervisory circuit integrated circuit monitors the system power supply and provides a chip reset signal in the event of an overvoltage condition. The integrated circuit ensures that undervoltage and/or overvoltage operations are monitored and secured from any damage to the components of a microprocessor powered system. A Reset output is generated when the supply voltage falls below the reset threshold level, or is disabled via an open drain output. In addition, when the reset is generated due to an overvoltage, the integrated circuit is designed to be disabled in order to protect the system.

The device consists of a voltage monitor and reset circuit that can detect both undervoltage and overvoltage conditions. The voltage monitoring circuit is designed to monitor the system’s power supply and provide a chip reset signal when the voltage exceeds the specified voltage. The integrated circuit also provides a hysteresis circuit which prevents chattering and prevents the reset output from being toggled during temporary voltage dips. The reset signal can’t be delayed more than 100 ms and is available at the output pin of the integrated circuit. This reset signal is further extended to the microcontroller to reset the microcontroller to its initial state and protect it from damaging operations.

The working principle of this integrated circuit is very simple. In normal condition where the voltage is stable, the integrated circuit is monitoring the voltage. When the voltage falls below the preset threshold, the integrated circuit starts to cycle the reset output. This reset output is connected to the reset pin of the microcontroller. When the reset output goes active, the microcontroller is reset to its initial state and is prevented from executing erroneous code.

The MAX6758UTTD0+T Supervisor is designed to meet the requirements of microprocessor-based systems demanding superior reliability. Its voltage monitoring and reset capabilities ensure that the system is continuously monitored and maintained to guarantee reliable operation. The reset circuit are also designed to guarantee that the operation of the microprocessor system is maintained when the supply voltage falls below the reset threshold level. The built-in watch-dog timer also ensures that in a lock-up situation, the system is reset to its initial working state. All these features make the MAX6758UTTD0+T ideal for automotive applications, areas that require high reliability, or power systems incorporating costly components.
