Power management integrated circuits (PMICs) are integrated circuits that enable increased energy efficiency and faster time-to-market in electronic designs. PMICs can provide greater than 95% power conversion efficiency, lower noise levels, and improved thermal performance. By utilizing this technology, system designers are able to reduce energy consumption while maintaining a stable electronics platform.

Supervisors are a specialized type of PMIC that monitors critical digital components such as microprocessors, digital logic ICs, and power supplies. MPQ6400DG-33-LF-Z is an advanced supervisor IC designed for high-voltage applications with an operating voltage range of 3V to 24V. The device features an ultra-fast voltage supervisor that activates within 35µs, providing highly reliable protection against power supply transients and aging.

The MPQ6400DG-33-LF-Z is designed to be used in a wide range of applications, from mobile phones and digital home appliances to industrial and automotive applications. It is a multi-functional device that integrates a voltage detector, voltage supervisor, power reset, and power on reset.

Application Fields

The MPQ6400DG-33-LF-Z supervisor is well suited for many types of applications, such as mobile phones, digital home appliances, automation, computer and peripherals, audio and video equipment, and automotive. It can be used to monitor the power supply voltage of microprocessors and ensure the safe operation of a system. The device can be used to detect any voltage changes in the system and initiate corrective steps if needed. The voltage supervisor can also be used to detect over-voltage and under-voltage conditions and initiate a power reset or power-on reset if needed.

The device is also well suited for applications requiring a high level of protection. It can monitor up to four external voltage lines to detect any variations in supply voltage and initiate corrective action if necessary. It also has an internal current sense circuit to detect over-current conditions. In addition, the device is capable of providing a power-on reset (POR) voltage of up to 24V and a reset threshold of up to 33V.

Working Principle

The MPQ6400DG-33-LF-Z is designed to monitor the power supply voltage of a system and initiate corrective action if needed. It has two main components: the voltage detector and voltage supervisor. The voltage detector is used to detect and identify any voltage changes in the system and to initiate corrective steps if necessary. The voltage supervisor is then utilized to detect any over-voltage or under-voltage conditions and initiate a power reset or power-on reset if needed.

The voltage detector uses a bandgap reference voltage to detect any changes in the voltage level. When the voltage reaches the specified threshold, it triggers a flag that can be used by the voltage supervisor to initiate corrective action. The voltage supervisor then checks the supply voltage level and will issue a reset or power-on reset if needed.

The MPQ6400DG-33-LF-Z is also capable of monitoring up to four external voltage lines and providing over-current protection. The device is able to monitor the current through each line and can detect any abnormal current values that could potentially damage the IC. If the current reaches beyond the maximum specified limit, the device will shut down the system and prevent any potential damage.

Conclusion

The MPQ6400DG-33-LF-Z is a specialized type of supervisor IC that is designed for high-voltage applications and can monitor the power supply voltage of a system. It features an ultra-fast voltage supervisor that activates within 35µs and provides highly reliable protection against power supply transients and aging. The device can be used in many types of applications, such as mobile phones, digital home appliances, automation, computer and peripherals, audio and video equipment, and automotive. It is also capable of monitoring up to four external voltage lines and providing over-current protection. By using this technology, system designers can achieve increased energy efficiency and faster time-to-market while ensuring the safe operation of their electronics system.
