As an innovative integrated device designed for advanced power management, the SI8252-IMR is a highly versatile PMIC (Power Supply Controllers, Monitors) applicable to various range of devices and applications, including automotive systems, consumer applications, industrial systems, medical and many more.

The SI8252-IMR is mainly composed of three key components, the two-phase DC-DC controller, two low-dropout (LDO) regulators, and internal real-time monitoring and safety circuitry. This combination allows for high-efficiency point-of-load power supply design, and helps reduce the power solution complexity, size and cost significantly.

The DC-DC controller of the SI8252-IMR provides high power delivery and high efficiency, which makes it highly suitable for automotive electrical components that require large current delivery. By regulating the output voltage and current through the internal power regulation circuit, the SI8252-IMR provides a flexible and stable voltage source with minimal input/output voltage noises.

The two LDO regulators are made up of a low noise LDO and a low quiescent current LDO that provide output to the primary, secondary, and back-up loads. Together, they can provide the necessary output voltage for different types of applications. They can operate over a wide range of input voltages and deliver an output precision of ±3%. In addition, their low dropout voltage feature allows them to maintain a regulated output voltage with an input voltage range of only 1.2V.

To ensure the performance, protection, and safety of the system or device, the SI8252-IMR also integrates a wide array of internal real-time monitoring and protection functions. This includes undervoltage/overvoltage protection, overcurrent protection, power good input monitoring, thermal shutdown, and brown-out protections.

In conclusion, the SI8252-IMR is a versatile PMIC suitable for a wide range of applications. By providing efficient power delivery and numerous protections, the SI8252-IMR enables the user to design a power supply solution with minimal complexity and cost. With its simple, efficient and reliable operations, the SI8252-IMR helps users reduce designs and maximize power efficiency.
