Introduction

In today’s electronics industry, the power management IC (PMIC) is an important part of system design and power management. Among the various kinds of power management ICs, the supervisor is the most important and widely used one. The MAX6722UTVHD3+T is a high performance supervisor IC used in a wide range of applications.

Field of application

The MAX6722UTVHD3+T has many advantages, making it suitable for various applications, such as:• Low voltage and system reset.• Automatically detect the threshold voltage of the system, and then reset the system when the voltage is abnormally low.• Automatically detect the threshold voltage of the system, and then control the internal power supply or other power sources to adjust the system’s voltage.• Supply power to the microcontroller when the system power fails, or when it needs to be reset.• Monitoring system temperature and detecting intelligent fan start/stop.• Regulate the system supply voltage.• Adapt to a wide range of operating temperature.• Monitor the operating frequency of microprocessors.• Supporting 5V/3.3V/2.5V and other voltage levels. • Support adjustable output voltage.• High-efficiency switching power supply protection. • Peak power and inrush current protection.• ESD protection.• Short-circuit protection. • Over-voltage protection.• Under-voltage protection. • Adjustable delay time and reset output time. • Low standby power consumption.• Small size and high integration. • High-temperature resistant and high-performance architecture.

Working principle

The MAX6722UTVHD3+T is mainly used for voltage monitoring and resetting. Its internal circuit has two stages: the first is the over-current protection circuit, the second is the reset circuit. The system reset is decided by the voltage comparator and the latch. If the voltage is lower than the set threshold value, it will trigger the reset function. The reset function can be manually activated by the reset pin, and it can also be automatically activated by the voltage comparator and latch. The interface of the MAX6722UTVHD3+T includes the power supply pin, reset pin and monitoring pin. The power supply pin provides power for the internal working circuit; the reset pin is used to manually output the reset signal; the monitoring pin is used to monitor the voltage of the system, and the voltage change will directly affect the voltage threshold of the reset signal, so that the reset circuit can perform the reset function in time.The MAX6722UTVHD3+T supports operating temperature up to 150°C. This high temperature resistance feature makes the MAX6722UTVHD3+T suitable for use in a wide range of applications, such as automotive and industrial environments.

Conclusion

The MAX6722UTVHD3+T is the leading PMIC - Supervisors. It offers many advantages, such as high temperature resistance, adjustable output voltage, low standby power consumption, peak power and inrush current protection, short-circuit protection and more. The MAX6722UTVHD3+T provides a reliable and efficient solution for providing power and voltage monitoring. Therefore, the MAX6722UTVHD3+T is widely used in a variety of fields, such as automotive and industrial electronics.
