The MIC4469ZWM is a dual MOSFET gate driver consisting of two low-side and two high-side outputs. It is designed to provide both flexibility and performance in applications where the gate drive of MOSFETs is required. The device is capable of driving both the high-side and low-side MOSFETs with an output of up to 6A peak and 4A RMS per channel, allowing for more efficient designs.

The MIC4469ZWM is primarily used to drive switching MOSFETs in a wide variety of common power topologies and circuits. Its design allows it to support both N- and P-channel MOSFETs, meaning it can be used in both synchronous and un-synchronized topologies. This makes it ideal for applications such as bridge rectifiers, invertors, buck converters, boost converters, and H-BRIDGEs.

The device features slew rate limiting, allowing for more precise control of the gate drive and ensuring that positive and negative spikes in the gate drive signals are suppressed. This helps to reduce power dissipation and increase overall efficiency. The MIC4469ZWM also integrates a number of additional features to enable system designers to better optimize their designs. These include temperature sensing, over temperature protection, thermal shutdown, an enable pin, and adjustable dead time.

At its heart, the MIC4469ZWM is powered by a high-performance dual bipolar power stage. This power stage allows for greater switching speeds resulting in improved performance and efficiency. The power stage also offers flexible output current sensing, allowing for more precise control of the power consumed by the device. This allows system designers to optimize the design of the system according to the specific application.

The MIC4469ZWM can be used in a wide range of applications and is optimized for gate drive requirements as low as 5V and as high as 18V. It is also capable of withstanding high voltages, up to 100Vrms, allowing it to be used in applications with high voltage requirements. Its design also allows it to be used in either slow or fast switching applications.

In summary, the MIC4469ZWM is an ideal solution for applications where robust gate drive is required. Its design yields highly efficient and precise power topologies, and its flexibility allows for its use in a wide variety of applications.
