Power management integrated circuits (PMICs) are used for a variety of applications, ranging from driving automotive power systems to portable electronics. A popular PMIC is the IRS21858STRPBF from Infineon, which is a dual-channel gate driver dedicated to driving high power MOSFETs. In this article, we will discuss the application field and working principle of the IRS21858STRPBF.

The Infineon IRS21858STRPBF is ideal for automotive and industrial applications, specifically when high reliability and fast switching speeds are required. It is designed to replace conventional MOSFET drivers and offers a high degree of integration, with integrated logic and a 3.3V or 5V LDO supply. With an output peak current of up to 2A per channel, the IRS21858STRPBF has been successfully tested in accelerating, decelerating and braking applications.

The IRS21858STRPBF operates by receiving an analog or digital input, which it then amplifies and interprets. When the input signal is within the low level logic threshold, the gates on the MOSFETs are activated, allowing electric current to flow through the circuit. When the input exceeds the threshold, the gates are deactivated and current stops flowing.

The IRS21858STRPBF also has several built-in protection features to ensure safe and reliable operation. These include over-voltage protection, over-temperature protection, under-voltage protection, over-current protection, and current limiting. It also has a fail-safe feature, which ensures the outputs remain off even when the input signal fails.

In addition to its protection features, the IRS21858STRPBF also has several other attractive features. It has a wide range of switching speeds from 500kHz to 1MHz depending on the load and input voltage. It also has a low quiescent current of just 5μA, which helps minimize power consumption and extends battery life. On top of that, the IRS21858STRPBF is also designed for low electromagnetic interference, making it suitable for automotive and industrial applications.

To summarize, the Infineon IRS21858STRPBF is a dual-channel gate driver designed for automotive and industrial applications. It is capable of driving high power MOSFETs with a peak current of up to 2A per channel. It has numerous protection features, a wide range of switching speeds, and a low quiescent current. All of these features make the IRS21858STRPBF a reliable, efficient, and cost-effective solution for driving high power MOSFETs.
