PMIC (Power Management Integrated Circuits) have become incredibly popular in today’s electronic devices. They serve a multitude of purposes, and one of these is Voltage Regulators – Linear. Within this category falls the S-1142A50H-E6T2U, an important PMIC voltage regulator. This device is unique in its ability to convert high voltage power sources into low and steady currents that are used in different types of circuits. The S-1142A50H-E6T2U application field and working principle can be broken down into different sections, in order for it to be more conveniently understood.

The S-1142A50H-E6T2U is part of a series of automatic constant current regulator (ACCR) integrated circuits that are intended for general purpose powered applications. They are best suited for battery-powered systems and highly efficient, often drawing only tens to hundreds of micro-amps. Each device is composed of an internal voltage reference, error amplifier, and a current mirror. These components work in combination to offer voltage and current regulation.

The S-1142A50H-E6T2U offers a wide input operation range from 4.50V to 25V. It also has high voltage output operation capabilities, up to 35V. The output voltage is adjustable through an external voltage divider to adjust for output current requirements. Its maximum output current is of 50A, making it ideal for battery powered systems, with its corresponding maximum voltage up to 32V and over-temperature protection up to 57°C.

The device also features over-temperature protection, in order to prevent any thermal overload damage, as well as current limit protection. Current limit protection is defined as the limiting of output current to a level that is safe for the device when it enters the region of the state. With the addition of a few components, the S-1142A50H-E6T2U can be configured as a constant current source or sink. Lastly, the device also features a wide temperature range, so that it may better withstand varying weather conditions.

The S-1142A50H-E6T2U provides non-isolated, linear voltage regulation. This means that the components interact directly with each other; when a device is connected, current flows through it, providing the necessary regulation. Most linear voltage regulators use voltage feedback for the purpose of controlling the output voltage and limit the amount of current that flows through the device. This device also features a temperature-independent source path, meaning that its temperature does not affect the flow of current, even in extreme temperatures.

The S-1142A50H-E6T2U application field ranges from automotive applications, such as electric power-assisted steering, automated driving control systems, electric vehicle charging, and off-road electric vehicles, to home appliance applications like washing machines, electric water heaters, and air conditioning systems. It is also used in industrial-related applications, such as industrial robots, autonomous vehicle drive systems, electric motors, and other precision system applications.

In conclusion, the S-1142A50H-E6T2U is the ideal choice when it comes to the need to manage and regulate voltage efficiently. Its wide range of applications and its adjustable output voltage makes it an ideal PMIC for many different types of powered devices. Its internal components work together to provide stable power for low and high voltage devices, keeping them safe and functioning with maximum efficiency. The device’s temperature independent source path and Over-temperature protection features add an extra layer of protection, ensuring the longevity and protection of the connected system.
