The IR2301SPBF is a Smart High- and Low-Side MOSFET and IGBT Driver that provides many features, including diagnostics and protection. It is a key component of many industrial and consumer applications as it provides advantages in reducing space and cost. This article will discuss in detail the application field and working principle of IR2301SPBF.

The IR2301SPBF is ideal for applications including automotive, medical and consumer products. Designed optimally for DC-DC converters, Uninterruptible Power Supplies (UPS’s), Local Motors, motor drives and all applications where the switching of power MOSFETs or IGBTs is necessary, the IR2301SPBF allows designers to reduce board space and cost, while providing better system reliability. It also provides various diagnostic and protection features, such as thermal shutdown protection, under-voltage lockout protection and over-current protection.

The IR2301SPBF is a state-of-the-art MOSFET and IGBT Driver with a range of features and benefits. Its integrated protections and diagnostics are not found on other devices. The features of the IR2301SPBF include:

• Integrated Input Clamp: The IR2301SPBF contains an integrated input clamp which provides overvoltage protection, allowing the device to continue operating when an overvoltage condition is present.
• Current Sense with Anti-Sat Protection: A programmable current sense circuit is included, which can be used to provide current monitoring and detection of a possible saturation caused by the load driver.
• Fast Return to Normal Operation: When the fault condition is removed, the IR2301SPBF can quickly return to normal operation, with a return-to-normal time of less than 10 microseconds.
• Shutdown Input Pin: The IR2301SPBF contains a shutdown input pin which can be used to disable the device in case of an overvoltage or overcurrent fault condition.
• Over-Temperature Protection: An integrated thermal protection circuit is included, which will protect the device from excessive temperatures.

The working principle of IR2301SPBF is quite simple. The chip can control the switching of power MOSFETs or IGBTs. It contains two output pins—INH and HI—which can be used to control the switching of low-side and high-side switches respectively. When INH is high, the low-side MOSFET is turned off, while when HI is high, the high-side MOSFET is turned off. When the chip is in shutdown mode, both the low-side and high-side MOSFETs are turned off. The chip also contains several diagnostic and protection features, including integrated input clamp, current sense with anti-sat protection, fast return to normal operation, and shutdown input pin.

In summary, the IR2301SPBF is an advanced MOSFET and IGBT driver that provides many features, including over-voltage and over-current protection. It is integrated with many diagnostic and protection features, allowing designers to reduce board space and cost. It is ideal for many applications including automotive, medical, and consumer products, as well as DC-DC converters, UPS’s, and motor drives.
