A8425EESTR-T, which belongs to the PMIC - Power Management - Specialized category, is a short-circuit protected, highly integrated DC/DC converter that provides both step-up and step-down voltage conversion for industrial and automotive applications. It contains MOSFETs and a global current limit protection that is suitable for the most demanding points of load in an unregulated input voltage range, for both asynchronous and synchronous switching modes. The device can be used for a wide range of applications, including but not limited to, motor control, battery charging, DC/DC power conditioning, unsuppressed output power sequencing, and DC/AC power conversion.

When it comes to the A8425EESTR-T’s application fields, it is ideal for developing and controlling automobile applications, where input supplies change continuously. This device can also be used to help industrial machines, robotics, just to list a few of its most common applications. Additionally, the A8425EESTR-T is designed for both DC and AC power conversion, making it extremely versatile for a broad range of uses.

Now, let’s discuss the A8425EESTR-T’s working principle. The device combines two synchronous, non-overlapping MOSFET switches, driven separately by two individual control signals, to regulate the output voltage. When the input voltage is higher than the output voltage, the device operates as a step-up converter. In this mode, it connects the output voltage to a capacitive input to increase the output voltage. On the other hand, when the input voltage is lower than the output voltage, the device operates as a step-down converter. In this mode, the device connects the output to ground to decrease the output voltage.

The A8425EESTR-T is also equipped with a global current limit protection, triggered when the output current is greater than the preset limit. This ensures the device does not operate in an excessively stressful condition when the current limit is exceeded, allowing for reliable operation for automotive and industrial applications.

In addition to its global current limit protection, the A8425EESTR-T also contains in-built short-circuit protection. This protects both the device itself and the connected equipment from damage due to short-circuits. The device also features a low quiescent current regime to minimize power consumption when the output voltage is low.

Overall, the A8425EESTR-T is a highly versatile, short-circuit protected, highly integrated DC/DC converter that can be used for a wide range of applications. It has the ability to operate in both step-up and step-down voltage conversion modes and is protected by a global current protection limit. With its low quiescent current regime, it is highly efficient and reliable in both automotive and industrial applications.
