Introduction to MAX6804US46D2+T Supervisors

The MAX6804US46D2+T is a supervisor family of highly integrated and programmable power-on reset (POR) and power-good (PGOOD) circuits for use in embedded systems. Supervisors, also known as reset ICs, are commonly used to maintain the reset state during power-up or power-down events in embedded systems or other electronic circuits. They can also provide protection against over-current, under-voltage, and over-temperature conditions.The MAX6804US46D2+T is a 6-output supervisor IC that can be programmed with one configurable set of configuration parameters in one architecture (non-volatile memory). It also offers a unique set of features including up to 2 integrated FETs, an adjustable reset time-out, and an advanced power-good circuitry. It is suitable for a wide range of applications including automotive, industrial, avionics, and medical.

Application Fields of MAX6804US46D2+T Supervisors

The MAX6804US46D2+T can be used in a variety of applications where a reset or a power-good signal is needed. They are suitable for use in DC-DC power supplies, battery power systems, digital logic systems, and non-volatile memory applications.In automotive applications, the Max6804US46D2+T can be used as a reset generator. The adjustable reset output voltage and timing make it suitable for automotive electronics such as engine control, body electronics, convenience systems, and more.In the industrial arena, the Max6804US46D2+T can be used to maintain the reset state in distributed power systems and is suitable for use in controllers, drives, and monitoring systems.In avionics applications, the Max6804US46D2+T can be used in communication systems and navigation systems. The integrated FETs can help minimize current surges that can damage sensitive devices and components.In the medical field, the Max6804US46D2+T can be used in portable ECG monitors, blood pressure monitors, patient monitors, and healthcare monitoring systems.The MAX6804US46D2+T is also suitable for use in a variety of consumer electronic and industrial applications such as process controllers, programmable logic controllers (PLCs), and portable devices.

Working Principle of MAX6804US46D2+T Supervisors

The MAX6804US46D2+T is an integrated power-on reset (POR) and power-good (PGOOD) circuit that can be configured to trigger a reset signal when system power is within and outside of predetermined parameters. The MAX6804US46D2+T works in two stages: initial power reset, and continual power-on reset (CPOR). For initial power reset, the MAX6804US46D2+T monitors and compares the input voltage with a pre-configured threshold. If the input voltage falls below the threshold, the circuit triggers a reset. After reset is triggered, the MAX6804US46D2+T will hold the reset until the input voltage has risen above the threshold. Once the voltage has risen above the threshold, the device will enter the CPOR mode and will continuously monitor the input voltage. If the input voltage falls below the threshold, the MAX6804US46D2+T will trigger another reset, thus keeping the system in a safe and stable power state.

Conclusion

The MAX6804US46D2+T is an integrated and programmable power-on reset (POR) and power-good (PGOOD) circuit for use in embedded systems. It is suitable for a wide range of applications including automotive, industrial, avionics, and medical applications. The MAX6804US46D2+T works by monitoring the input voltage and triggering a reset if the voltage falls below a pre configured threshold. The MAX6804US46D2+T is a reliable and versatile reset IC that can be used to provide power reset and power-good in a wide variety of applications.
