PMIC - Supervisors

PMIC (Power Management IC) refers to an integrated circuit specifically designed for power management in electronic systems. PMICs are designed to provide the power supply and voltage regulation needed by the components of the target system. The MAX6734AKASYD3+T is a high-voltage PMIC supervisor integrated circuit from Maxim Integrated.

Application Field

The MAX6734AKASYD3+T is designed for high-voltage systems that require a precision low-voltage reference and multiple power-good indicators. It is particularly well suited for Li-ion and Li-polymer battery-powered systems. It is an excellent choice for monitoring Li-ion systems that require a stable, low-voltage supply. It is also an ideal choice for automotive and industrial applications, where robust and reliable power supply monitoring and management is essential.

Working Principle

The MAX6734AKASYD3+T contains two independent overvoltage comparators, one low-voltage comparator, and one reset circuit. The overvoltage comparators provide economical voltage monitoring of the high-voltage rail and the low-voltage reference output. The low-voltage comparator monitors the voltage at the battery cell, providing an early warning of potential faults. The reset circuit monitors the reset voltage and provides an adjustable reset signal.

The MAX6734AKASYD3+T also features a selectable reset active, auto-delay and manual reset delay, and a wide range of programmable voltage thresholds. With the ability to monitor and protect up to five individual voltage rails, the MAX6734AKASYD3+T can provide a comprehensive solution for system protection.

Conclusion

The MAX6734AKASYD3+T is a high-performance, high-voltage PMIC supervisor integrated circuit. It is ideal for monitoring and protecting high-voltage and low-voltage systems. With its variety of programmable configurations and adjustable reset signals, the MAX6734AKASYD3+T is the perfect choice for automotive and industrial applications that require accurate and reliable power management.
