IR2153 is a single high- and low-side driver gate driver integrated circuit (IC). The gate driver is typically associated with power management integrated circuits (PMICs) or gate drives. It is designed to be used in a wide range of applications, including those requiring a full bridge configuration. This Article provides an overview of the IR2153\'s application field and working principle.

IR2153 Application Field

The IR2153 gate driver is mainly used in full bridge circuits. These circuits are used for power control applications, typically in low-power motor control applications, such as automotive and industrial inverters, solar inverters, motor controls, HVAC systems, and the like. In such applications, the full bridge configuration is often preferred due to its ability to provide better efficiency and reliability, as well as its superior thermal stability. As a result, the IR2153 is well-suited for applications such as creating a full bridge rectifier circuit, and as a power switch in three-phase motor control systems.

The IR2153 gate driver is also used in high-power systems, such as high-efficiency AC-DC and DC-DC converters. These systems are typically designed to provide higher efficiency, meaning they require the ability to accurately control switching of high-voltage loads. The IR2153 is well-suited for such applications due to its high-speed switching and wide operating voltage range (up to 100V). The IR2153 is also able to drive high-current MOSFETs and IGBTs, enabling it to be used in higher power systems as well.

IR2153 Working Principle

The IR2153 gate driver is comprised of two independent driver circuits, each with its own high-side and low-side transistor drive outputs. The circuit uses P-channel and N-channel power MOSFETs to drive the outputs. Each output is controlled by its respective input: a logical high on the input will turn the power MOSFETs on or off, depending on the polarity of the output and the MOSFETs connected. The inputs can be either TTL compatible logic signals or open-drain digital logic signals.

The IR2153 is enabled via the EN pin. When enabled, the gate driver will operate in the "Active" mode, where it will continue to drive the outputs in accordance with the logic level at the inputs. The maximum output voltage is limited to 100V, and the maximum output current is limited to 200mA. The gate driver also includes an internal voltage regulator, which allows it to maintain a constant output voltage regardless of the input voltage. This is an important feature, as it allows the IR2153 to be used in applications with wide range of input voltages.

The IR2153 gate driver is designed to provide an efficient and reliable solution for powering MOSFETs and IGBTs in high-performance systems. With its wide operating voltage range, high-speed switching capabilities, and internal voltage regulator, it is able to support a variety of applications, including those requiring a full bridge configuration.
