Power Management Integrated Circuit (PMIC) is a key component of electronic systems. It includes multiple power sources and components to fully control, provide signals and electrical power for the entire system. Among them, Gate Drivers play an important role in controlling the operation of power components in the system. This article will discuss the application field and working principle of the FAN7190MX-F085P Gate Driver.The FAN7190MX-F085P is designed to control the operation of N-channel Metal Oxide Semiconductor Field Effect Transistor (MOSFET) and Insulated Gate Bipolar Transistor (IGBT) devices. It has excellent monotonic and load dump transient testing capabilities and complies with the automotive electromagnetic compatibility (EMC). It has a wide operating voltage range of 8.5V to 35V and a wide operating temperature range of –40°C to +125°C. The FAN7190MX-F085P employs an internal fault protection circuit and an adjustable dead time circuit that can effectively reduce reflected current and improve the reliability of power devices.In terms of application field, the FAN7190MX-F085P is widely used in automotive power systems such as electric tachographs and automotive start-stop systems. It also finds application in industrial motor control systems, home appliances, solar cells and other energy-related charging and discharging systems.The FAN7190MX-F085P works by controlling the power devices to turn on or off, thus realizing effective control of the load current. It has two state outputs, the high side and the low side. The high side is driven by the high-side driver, while the low side is driven by the low-side driver. Both high- and low-side drivers are connected to an inverting control signal to directly control the power devices. The high-side driver is also connected to a floating dropout sensing signal (VFET) which senses the voltage at the power device’s source, thus intelligently detecting whether the power device is successfully connected and enabling the device to enter an idle state if the power devices are disconnected.In summary, the FAN7190MX-F085P is a Gate Driver that is widely used in automotive and industrial applications for controlling power devices. It offers a wide operating voltage range, a wide operating temperature range, adjustable dead time, built-in fault protection and intelligent power device connection sensing. It is highly reliable and well suited for driving various power components in various applications.
