Introduction
IRS2158DPBF is a monolithic dual-channel gate driver integrated circuit (IC). It has been designed with an emphasis on providing a high-speed gate drive capable of driving high-side and low-side N-channel MOSFETs (NMOS or PMOS) or BJT devices. It is an efficient solution for low side configurations of push-pull power switching applications like motor control and LED lighting.

Application Field
IRS2158DPBF is mainly used for the implementation of Intelligent Power Modules (IPMs) for motor control and LED lighting applications. It is a dual N-MOSFETs low side driver designed for high current, low voltage operation. The functioning is optimized for driving power MOSFETs in a wide range of lighting and motor control applications. It is particularly suitable for DC-to-DC converters, AC-DC converters, DC motor drives, DC power supplies and non-isolated DC-DC converters. The dual-channel output current can be up to 4A.Working Principle
IRS2158DPBF features a Schmitt-trigger input for improved noise immunity, resulting in excellent jitter performance and low possibility of false triggering. The output stages feature a rapid, high performance structure with soft turn-on, fast turn-off, and low gate impedance. Additionally, programmable dead-time delay between the two output drivers provides good control of the conduction time of each power stage of the power application.The device also features integrated protection features, such as Gate Driver over-current limit and gate turn-off to prevent high voltage and drain current during over-current conditions. Additional protection includes a temperature sensing circuit, to avoid over temperature conditions. The driver also includes an under-voltage reset logic and a power good logic signal.Conclusion
IRS2158DPBF integrated circuit offers a high-speed and efficient gate drive solution for motor control and LED lighting applications and is a perfect choice for low side configurations of push-pull power switching applications. With a wide range of integrated protection features, it provides a reliable gate drive solution perfectly suited for LED lighting, motor control and other power switching applications.
