The MIC4479YME-T5 is ideal for use in a variety of automotive applications, such as powertrain and gate protection systems. This versatile gate driver IC supports a wide range of input voltages (5V~40V) and comes in a space-saving, low-profile SO-10 housing. It features a patented high-side/low-side output protection circuit, as well as on-chip ESD protection, making it well suited for automotive environments. Additionally, this IC also features a sense voltage pin that enables a common-mode output offset adjustment, allowing optimal tuning of the driver micro-BOOST loop and damping of the LC filter, allowing for a reduction in the EMI noise emission.
Further, the MIC4479YME-T5 is capable of delivering a maximum output current of 7A, higher than most competing gate driver ICs. It also supports a wide range of input voltages (5V~40V) and comes with a comprehensive set of integrated diagnostic features. The built-in slew rate control allows for faster output transition during PWM-mode operation, and the integrated temperature monitoring and over-temperature protection can help design for reliable operation over the wide range of temperatures found in automotive environments.
Working Principle
The MIC4479YME-T5 is a three-phase gate driver IC specifically designed for automotive applications. It is designed to provide high efficiency and support a wide range of input voltages. The IC comprises a gate driver, a gate protection circuit, an over-temperature protection circuit, and a slew rate control circuit. The gate driver IC is based on a half-bridge configuration, with a built-in protection circuit to protect the output FETs from both overcurrent and overvoltage. The protection circuit features a peer-to-peer interface, and is comprised of two independent regulating devices, one connected to the low-side FET and one connected to the high-side FET.
The MIC4479YME-T5 employs an internal half-bridge micro-BOOST loop to ensure that both the high-side and low-side FETs are energized with a balanced PWM timing. The micro-BOOST loop is designed to minimize dead-times by ensuring that the FET conduction and switching times are centered about the PWM period. Additionally, the slew rate control circuit allows for faster output transition during PWM-mode operation, making this gate driver IC suitable for high switching frequency applications.
The IC also features a sense voltage pin that enables a common-mode output offset adjustment. This allows the micro-BOOST loop to be optimized and reduces the amount of EMI noise emitted by the IC. The sense voltage pin also allows the output equivalent series resistance (ESR) to be accurately tuned, allowing for greater system accuracy. Additionally, the MIC4479YME-T5 includes an on-chip temperature monitoring and over-temperature protection to ensure reliable operation over a wide range of temperatures.
In conclusion, the MIC4479YME-T5 is an excellent gate driver IC specifically designed for automotive applications. It has a wide range of features, including high efficiency, wide input voltage range, peer-to-peer protection circuit, sense voltage pin, over-temperature protection, slew rate control circuit, and more. It is ideal for use in a variety of automotive gate applications, such as powertrain and gate protection systems.
