The X4165PZ-2.7 is a power management integrated circuit (PMIC) commonly used for supervisors. This PMIC is an ideal choice for applications requiring both high-efficiency regulator and power distribution.

The X4165PZ-2.7 integrates an adjustable 2.7V ideal diode regulator, power distribution multiplexer to regulate 5-6V and overvoltage protection. This PMIC offers coverages ranging from 1.1V to 5.5V. It also features thermal protection, output-current limit, and off-state active discharge.

One of the most popular applications of X4165PZ-2.7 is in automotive applications where a wide input voltage range is required. Automotive applications require stable power delivery especially during power transitions. The adjustable diode regulation of this PMIC allows a stable power supply regardless of the input voltage. It is also suitable for industrial or consumer applications with power supply requirements up to 5.5V.

The working principle of X4165PZ-2.7 is simple. When input voltage is greater than output voltage, the circuit is in linear regulation mode and the adjustable 2.7V ideal diode regulators control the output voltage. If the input voltage drops below the output voltage, the circuit will automatically switch to the power distribution multiplexer to regulate the power supply. The power distribution multiplexer is connected to a predetermined set of power rails, allowing the PMIC to automatically adjust the voltage for different input conditions.

The X4165PZ-2.7 has several features that make it suitable for supervisors. It integrates several safety features such as overvoltage protection and thermal protection. These safety features are designed to protect the integrated circuits from damage due to sudden changes in input voltage. It also includes output-current limit and off-state active discharge for improved protection. Additionally, the adjustable 2.7V ideal diode regulator allows for a reliable power supply even with changing input voltage.

Overall, X4165PZ-2.7 is an ideal choice for supervisors due to its adjustable 2.7V ideal diode regulator, overvoltage protection, thermal protection, and multiple power rails. It is suitable for automotive applications and other industrial or consumer applications with power supply requirements up to 5.5V. The features of this PMIC make it a reliable and efficient supervisor for any application.
