PMIC - Gate Drivers

The EL7242CNZ is a high-performance gate driver IC from Elmos E-Motor Drive, intended for use in automotive motor control applications, or any other application needing to drive both high- and low-side power MOSFETs with high current and minimum propagation delay. The chip combines advanced mixed-signal technology, leading-edge digital and low-power mixed-signal architecture, and proprietary precision analog processing techniques to achieve a balance between speed and efficiency.

The EL7242CNZ is based on a single-chip integrated circuit, composed of four synchronous gate drivers operating with inputs of logic levels that provide drive and protection to a low-side power MOSFET and a high-side power MOSFET. The device consists of two logic-level high-side drivers and two rail-to-rail analog drivers. The logic-level drivers can handle up to 24V for high-side applications and the rail-to-rail drivers can handle up to 30V for low-side applications.

The EL7242CNZ gate drivers offer several advantages over conventional gate drivers. The most significant benefits are improved efficiency, higher drive current capabilities, and faster thermal proof characteristics. Additionally, the gate drivers can significantly reduce power consumption by employing low-power consumption techniques while still providing accurate and high-speed switching.

The working principle of the EL7242CNZ is based on a multi-channel, voltage-controlled device that provides high-speed and accurate gate control for both high-side and low-side power MOSFETs. The circuit switches between high and low output states in response to an input signal, and can drive current up to 30A. In addition, the driver features an integrated thermal protection function that can prevent overheating of the devices and reduce the need for external thermal management components.

The power MOSFETs the IC is designed to drive can be used in a variety of applications, including automotive control, industrial, and audio power amplifier design. This makes them suitable for both wide-range and specialty applications, where precision and fast response are important. Additionally, the EL7242CNZ also provides overload protection, over temperature protection, and under-voltage lockout (UVLO) protection.

EL7242CNZ gate drivers are designed to maximize the useful life and reduce the cost associated with operating multiple power MOSFETs. The driver provides a level of accuracy, speed, and protection that makes it ideal for use in automotive motor control applications, as well as any other application requiring fast and accurate power MOSFET gate control. As a result, the EL7242CNZ is a great choice for designers looking to improve the overall efficiency and reliability of their application.
