Power management integrated circuits (PMICs) are designed to allow the optimum performance of an electronics system by delivering cleaner, more efficient and current-regulated power and by controlling or monitoring certain power parameters. They are critical elements for embedded systems, providing the necessary current and protecting the downstream circuits from unwanted transients. Among PMICs, typical power distribution switches are employed in most applications, both digital and analog circuits. Such switches are characterized by their high level of integration and wide range of features, making them suitable for various embedded systems applications.

VNH2PTTR-E is a power distribution switch developed by STMicroelectronics that integrates a high-side DMOS power switch and a low-side DMOS switches in a single package. It is designed to deliver power to the load while monitoring voltage, current and temperature. Featuring a high tolerance to inrush current, a hysteretic start-up circuit, and low quiescent current, it offers excellent switch performance and protection for the load. It is capable of controlling, routing, and regulating the power supply to and from the load, thus enabling embedded systems with optimal power efficiency and reliabiity.

The VNH2PTTR-E operates by configuring the control signal, then adjusting the resistor connected to the voltage input and current monitor pins to set over-current and over-temperature thresholds, and finally setting the slew rate control resistor connected to the output of the switch. To ensure proper operation, a thermal shutdown feature is incorporated which trips when the device power dissipation reaches a specified limit.

The VNH2PTTR-E can be used in a variety of embedded applications, including power management for LED lighting, automotive systems, digital signage, connectivity devices, and automation systems. It is available in two common surface mount packages, allowing for easy assembly and providing designers with a wide range of versatility in board design. The VNH2PTEER-E offers advanced monitoring, protection and reliability features which make it the ideal IC for advanced embedded designs.

In summary, the VNH2PTEER-E is a high-performance power distribution switch that offers a high level of integration and a wide range of features. It can be used in a variety of embedded applications, providing the necessary current and protection for downstream circuits while monitoring voltage, current and temperature. Its advanced monitoring and protection features make it an ideal choice for advanced embedded designs.
