Working principle

The ISL6146EFUZ-T PMIC uses multiple internal sub-circuits to provide superior performance and reliability. It is comprised of two voltage supervisors, four step-down converters, four ideal diodes, and one LDO. The voltage supervisors use a detection and comparison circuit to monitor and protect the voltages across the power supply and alert the system whenever an unsafe voltage is detected. The voltage supervisors can detect an over voltage, under voltage, and reverse voltage protection, keeping the system safe from any potential power spikes or drops.

The four integrated step-down converters regulate the voltage supply within the system, converting a higher voltage to a lower voltage as required. The converters are capable of supplying up to 4A of output current, allowing them to meet the power needs of multiple subsystems within the system. The integrated ideal diodes provide a fast, low impedance pathway between the source voltage and the load. The diodes can be configured to operate in either a voltage triggered or delay triggered mode. Finally, the integrated LDO supplies up to 1A of current, and can be used to power a wide range of components that require a constant, low voltage.

The ISL6146EFUZ-T is an advanced, highly efficient PMIC that provides superior performance and reliability. It is the ideal solution for a wide range of low power subsystems, such as automotive and mobile applications, robotic controllers, home and building automation systems, wearable devices, and battery management systems. Its multiple internal sub-circuits provide the superior performance and reliability that make it such an ideal solution for advanced voltage supervision, power management and ideal diode applications.
