Introduction

ISL6146DFUZ is an integrated circuit (IC) from Intersil that functions as a PMIC - OR Controllers, Ideal Diodes, a power supply control voltage regulator. It is an integrated unit composed of high-side and low-side MOSFETs and ideal diode, providing integrated over-voltage protection and reverse polarity protection for applications where load transient conditions exceed the capabilities of the system power supply. It is optimized for high power applications and is easy to use because of its integrated protection features and adjustable dual supply voltage levels.

Application Field and Working Principle

ISL6146DFUZ provides dual channel over-voltage, over-current and thermal protection. It designed to be a PMIC-OR Controllers, Ideal Diodes and makes possible multiplexing of system power supply with logic power supplies and ensures safe operation when the power supply fails or exceeds rating of the system. Both the high-side and low-side MOSFETs are integrated in one package, providing two independent MOSFETs with over-voltage and over-current protection to guard against system damage. All ISL6146DFUZ devices also have a thermal protection feature which activates when the device temperature rises above the rated limit. This feature prevents the device from being damaged due to excessive power dissipation.

ISL6146DFUZ main application fields are: automotive and industrial displays, power supplies, PCs, monitors and other electronic and electrical parts. The load transient protection reduces the amount of time it takes to recover from abnormal conditions, and the adjustable dual supply voltage levels provide for lower power consumption and increased reliability. Ideal diodes are used to prevent excessive currents from flowing on the sense line, and to provide pre-load protection with no external components. The adjustable voltage levels allow the user to chose the best voltage level for the particular application.

The function of the ISL6146DFUZ consists of two independent high-side and low-side MOSFETs with over-voltage, over-current and thermal protection. The high-side and low-side MOSFETs provide two independent power pathways. The first pathway is the power supply, which supplies power to the load through the high-side MOSFET. The second pathway is the sense line, which senses the load voltage and maintains it within the over-voltage/over-current limit. In the event of an over-voltage or over-current condition, the sense line trips and disables the high-side MOSFET, thus stopping the power supply. The low-side MOSFET is connected to the load in parallel, and provides additional protection by limiting the amount of current that can flow through the load. The ideal diode (ID) is the third constituent part, allowing only the current necessary for the load to flow, and preventing excessive current from flowing on the sense line.

Conclusion

In conclusion, the ISL6146DFUZ is a PMIC - OR Controllers, Ideal Diodes integrated circuit that provides an efficient, reliable and integrated control system for applications requiring over-voltage protection. It is an integrated unit composed of two independent high-side and low-side MOSFETs and a ideal diode, providing dual channel over-voltage, over-current and thermal protection. The adjustable dual supply voltage levels reduce power consumption while the ideal diode provides pre-load protection with no external components. ISL6146DFUZ can be used in multiplexing of system power supply with logic power supplies and in automotive and industrial display power supplies, PCs, monitors and other electronic and electrical parts. The main advantage of ISL6146DFUZ is the integrated protection features and adjustable dual supply voltage levels, providing safety and reliability even in extreme conditions.
