Power management integrated circuits (PMICs) are a class of integrated circuits designed to help regulate, monitor and manage the power levels of different components on a circuit board. The XC6122D346MR-G is a PMIC Supervisory circuit from Renesas Technology specifically designed to help control and monitor power levels in digital circuits. It is used in a variety of electronic systems, from consumer electronic products to industrial equipment.

Key Features

The XC6122D346MR-G is a voltage supervisory circuit, which is a type of PMIC. It monitors and maintains voltage levels within a certain range. It has a wide range of features, including:

• 1.65V to 4.63V operating voltage
• 1.2V to 4.2V pre-set voltage
• Over-voltage and discharge protection
• Under-voltage detection
• Analog and digital monitoring of voltage levels
• Interrupt output with programmable delay
• Low current consumption while operating

Application Field

The XC6122D346MR-G is typically used to protect digital circuits from over-voltage and under-voltage. As an example, it can be integrated into a circuit containing a processor or microcontroller. The processor would be supplied with power from a voltage regulator, which is in turn supplied with electric power from a battery or mains. The XC6122D346MR-G would then be place in between these two components to monitor and maintain the voltage levels at the processor. This allows the processor to be supplied with consistent and stable power, which prevents it from experiencing too low or too high power levels.

Furthermore, the XC6122D346MR-G also has applications in portable devices. It is designed to be powered at very low current, which allows it to be used in battery powered devices. This feature is important for mobile phones, laptops and other portable electronics, as they must operate at very low current while still being able to monitor and maintain power levels.

Working Principle

The XC6122D346MR-G operates by monitoring the voltage levels. It achieves this by using a pre-set voltage threshold. If the voltage level is above this threshold, the XC6122D346MR-G will generate an output signal. If the voltage level is below this threshold, the XC6122D346MR-G will generate an output signal. This signal can then be used to control the voltage supply to the processor or digital circuit.

The XC6122D346MR-G also has an over-voltage protection feature. This feature is important as it prevents the processor from experiencing too much power, as too much power can damage the processor. The XC6122D346MR-G can quickly detect an over-voltage state and instantly shut off the power supply to the processor.

Finally, the XC6122D346MR-G also has a programmable delay feature. This feature allows the user to control the delay between the input signal and the output signal. This can be used to add an extra layer of protection to the processor, as the delay allows the user to configure the processor’s power supply to turn off sooner, allowing less time for the processor to be damaged by over-voltage.

Conclusion

The XC6122D346MR-G is a PMIC Supervisory circuit designed to monitor and maintain voltage levels in digital circuits. It has a wide range of features, including an operating voltage of 1.65V to 4.63V, over-voltage and under-voltage protection, analog and digital monitoring of voltage levels, and a programmable delay. It is typically used to protect processor and microcontroller circuits, as well as in a variety of battery powered devices. By using the XC6122D346MR-G, system designers can ensure that the circuits they are designing are reliable and stable, providing consistent power levels to the components on the circuit board.
