The MC33064DM-5R2 is a type of primary-side monitoring PMIC supervisor. It offers two functions: reset monitoring and overvoltage protection, with both functions being carried out in a single package. This makes the MC33064DM-5R2 a cost-effective solution for controlling fault conditions across a variety of power systems and for implementing a reset/power-on sequencing circuit.

Application Field

The MC33064DM-5R2 is suitable for wide range of applications including:

  • Power supplies for consumer, industrial and automotive systems,
  • Powering FPGA and microcontroller systems,
  • Monitoring power lines in systems with multiple independent AC inputs,
  • Controlling fault conditions in system power management architectures,
  • Reset generator circuits.

The MC33064DM-5R2 can be used to ensure the power-on sequencing and healthy system operation in computer-based systems and other microprocessor-controlled systems, such as motor controllers, telecommunications systems and motor monitoring systems.

Working Principle

The MC33064DM-5R2 has two main components: a voltage supervisor and an overvoltage protection circuit. The voltage supervisor is designed to detect if the power supply is pulsing erratically or if the supply voltage falls below a set threshold. When this happens, an open-drain output is activated, signalling an active reset. The overvoltage protection circuit operates in the reverse direction and will detect if the supply voltage rises above a set threshold. If an overvoltage condition occurs, an open-drain output is activated, signalling an active overvoltage protection. Both of these signals are open-drain and can be used to drive a reset signal or supply a control signal to the system’s power switch.

The MC33064DM-5R2 has several features that make it suitable for a wide range of applications:

  • Adjustable reset/overvoltage thresholds,
  • Built-in hysteresis, allowing for greater accuracy and less output noise,
  • Fast reset times, allowing for faster system response,
  • Wide input voltage range, allowing for flexibility in power supply design,
  • High output current, allowing for driving high capacitive loads,
  • Internal bandgap reference, allowing for improved accuracy and system performance.

The MC33064DM-5R2 is available in various package options, including surface mount and through-hole packages. This makes it suitable for a wide range of different applications, from small handheld devices to larger systems in industrial and automotive applications.

Conclusion

The MC33064DM-5R2 is a PMIC supervisor which combines the functions of reset monitoring and overvoltage protection in a single package, making it a cost-effective solution for controlling fault conditions in system power management architectures. It has a wide input voltage range and fast reset times, allowing for faster responding systems. It features adjustable reset/overvoltage thresholds and built-in hysteresis, allowing for greater accuracy and less output noise. With its various package options, the MC33064DM-5R2 is suitable for a wide range of different applications, from small handheld devices to larger systems in industrial and automotive applications.
