Power Metal-Oxide Semiconductor Field Effect Transistor (MOSFET) is an integrated-circuit based half-bridge MOSFET driver optimised for controlling a half bridge powered by an Auxiliary Power Supply (APS).IR2131 is an example of PMIC (Power Management Integrated Circuit) gate driver that is targeted for a wide variety of applications.

The IR2131 is a high current gate driver that combines a MOSFET driver (MOSD-TEC) with two channels of high-side/low-side drive circuitry. It is optimized for reliable switching performance and high system efficiency. The integrated driver provides a high level of drive current to the gate of the MOSFETs. As a result, the efficiency of operation is improved, while the power dissipation is lowered.

IR2131 is especially suitable for applications such as motor control, test and measurement, load switching, and other purposes that require a high level of switching performance. The IR2131 is ideal for applications with limited board space, as it integrates the functionality of a high-side/low-side driver and a MOSFET driver in one package.

The working principle of the IR2131 is based on the MOSD-TEC (MOS Transconductance-to-Envelope Control) design. This technology provides a high level of current to the MOSFET gates and results in higher efficiency and lower power dissipation. The IR2131 has two channels of high-side and low-side drive current and can provide up to 3A of current to drive the MOSFETs. Additionally, the IR2131 has integrated protection features such as undervoltage lockout and overcurrent protection.
