The MIC4420ZN is a robust, cost-effective gate driver with built-in isolation. It is specially designed to drive N-Channel MOSFETs, IGBTs, P-Channel MOSFETs and Cascodes, making it suitable for a wide array of applications. It is often used in systems operating at high temperatures, high-power supplies, low-voltage and high-power switching applications. The MIC4420ZN is categorized as a PMIC - Gate Driver.
The MIC4420ZN has a wide range of features, including low power consumption and a fast propagation delay of 15ns. It also features built-in over-voltage and over-current protection, as well as a built-in dead-time of 25ns for improved efficiency. Additionally, the device is designed with an optimized gate-drive voltage that can support three-level inverters.
The MIC4420ZN’s main characteristics are its high-current capacity, low-resistance power MOSFETs and fast response time. It can drive up to 6A of any type of MOSFET and IGBT; this current level can be generated without any external gate-driving devices. Moreover, the MIC4420ZN has a wide range of input voltages (3V to 40V) that enable it to support low-voltage applications. Additionally, its low quiescent current in shutdown mode of 1µA makes it an ideal choice for battery operated devices which need to conserve power when in a low-power state.
The MIC4420ZN utilizes an internal common-mode transformer to isolate its gate-drive circuit and power supply. This eliminates the need for external galvanic isolation, reducing the parts count, board space, and cost for the system. It also uses an internal bootstrap diode to increase the gate voltage and eliminate the need for an external bootstrap capacitor.
The MIC4420ZN is designed to operate in both continuous and intermittent modes. It can use an input voltage of up to 40V, and can be used in both forward and reverse topologies. The device is also temperature-resistant and capable of operating at temperatures up to 150°C.
The working principle of the MIC4420ZN is as follows: when the IC is enabled, the internal FET driver turns on the gate of the external MOSFET. The MIC4420ZN provides a fixed amount of gate drive current, which turns on the gate voltage and decreases gate charge transit time. Once the MOSFET is on, the MIC4420ZN will maintain the gate voltage until it is disabled.
In summary, the MIC4420ZN is a robust, cost-effective PMIC - Gate Driver that is suitable for a range of high-power switching applications. It has a wide range of features which make it an ideal choice for low-voltage and high-power circuits. Its fast internal diode and common-mode transformer provide excellent isolation and its built-in protection mechanisms ensure system safety. Additionally, its wide range of input voltages and fast response time make it well-suited for use in battery operated devices.
