The MIC44F19YML-TR is a versatile and high-performance, high-side and low-side power MOSFET driver from the MIC44F-series manufactured by Microchip Technology. It is a quad non-isolated MOSFET driver for driving external N-channel MOSFETs. The 1.2A source and 3A sink current capability and a maximum operating supply voltage of 28V makes it ideal for applications that require a wide range of power MOSFETs. In addition, the MIC44F19YML-TR also supports both single-ended and differential output modes, allowing for customers to choose between control of both voltage and current.This MOSFET driver can be utilized in a wide range of applications due to its flexibility and high level of performance. Examples of these applications range from general AC/DC power supplies, to motor and lighting control systems, to power conversion applications such as solar and wind power systems. Additionally, the driver is suitable for high-voltage applications, with a maximum operating voltage of 28V and a maximum power dissipation of 223mW. Furthermore, the MIC44F19YML-TR supports both low-power forward and reverse body diode protection and series gate resistor protection, making it ideal for high-side switching applications.The MIC44F19YML-TR also offers several features that allow it to effectively drive both high-side and low-side MOSFETs, while operating reliably in a wide range of operating temperatures. For example, the low supply current of only 450μA at 25℃ and an extremely low input transition-time of 6.2ns allows for faster switching speeds, while the soft-start and synchronization capabilities reduce the inrush current during start-up and reduce the effect of electromagnetic interference. Additionally, the driver has an adjustable switching frequency, allowing users to optimize the switching speed, while the integrated thermal protection feature prevents the driver from overheating.In terms of its working principle, the MIC44F19YML-TR is a non-isolated gate driver, meaning that it does not use isolated voltages. Instead, it uses a single operating voltage, along with logic-level inputs, to control the gate voltages of both high-side and low-side MOSFETs. The inputs are supplied with a logic-level signal, and the output of the driver will switch the associated MOSFET according to the signal. This enables the driver to be used in a wide range of applications, from lighting and motor control, to solar and wind power conversion.Finally, since the MIC44F19YML-TR offers a wide range of features and operating parameters, it can be used as a standalone unit, or as a part of a larger system. For instance, it can be used as part of a power supply system, a motor and lighting control system, or a solar and wind power conversion system. Furthermore, since it is designed to operate reliably in a wide range of temperatures, it can be used outdoors, or in any environment where extreme temperatures may be present. In short, the MIC44F19YML-TR is a highly versatile, high-performance power MOSFET driver that can be used in a wide range of applications.
