The MIC4469BWM TR is an Intelligent Power Module (IPM) gate driver from the MIC4400 family of IPMs manufactured by Micrel Semiconductor. It is designed to provide a complete, cost-efficient, and high-performance solution for driving power MOSFETs and IGBTs in Industrial Motor Control, Server and Storage, Automotive and Automotive Thisis, and Uninterruptible Power Supply applications.The MIC4469BWM TR IPM gate driver has several features that make it a great choice for these applications. It includes two independent high-side and two independent low-side gate drivers in a single package, low operating and standby current consumption, and low voltage operation. The MIC4469BWM TR also offers on-chip Smart Gate Control (SG), which dynamically adjusts gate drive current based on device status, gate capacitance, and fast overcurrent response. It also provides overvoltage protection, thermal-shutdown protection, and a built-in power-on reset circuit.In addition, the MIC4469BWM TR IPM gate driver provides a number of features that make it ideal for power MOSFET and IGBT gate driving applications. It offers a high slew rate of up to 250V/μsec, fast gate settlement time of 2μsec (typical), an adjustable gate driver current of up to 6A, and a high temperature operating limit of 175 °C. It also offers overshoot protection and an adjustable dead time delay of up to 20 μsec.In terms of its working principle, the MIC4469BWM TR IPM gate driver uses a 5V DC supply input with an integrated 5V DC regulator, allowing it to drive power MOSFETs or IGBTs with a wide range of gate voltages. Its two-independent high-side (VHS) and low-side (VLS) gate drivers use power MOSFETs and IGBTs, respectively, to support up to 6A of each device. The onboard switching controllers monitor the current, voltage, and thermal status of the power devices in order to provide an optimized gate drive current to ensure high efficiency.The MIC4469BWM TR IPM gate driver is an ideal solution for driving power MOSFETs and IGBTs in Industrial Motor Control, Server and Storage, Automotive and Automotive Thisis, and Uninterruptible Power Supply applications. Its features such as low operating and standby current consumption, low voltage operation, fast gate settlement time, adjustable gate drive current, high temperature operating limit, overshoot protection, and adjustable dead time delay make it an ideal choice for these applications.
