The M63993FP is an integrated gate driver designed to control and drive MOSFET and IGBT devices. It is an integrated power management integrated circuit (PMIC) designed specifically for use with power MOSFETs and IGBTs. It offers a wide variety of features, including power-on reset (POR), an integrated driver core with 5 A output current, adjustable deadtime and voltage-shift control for high-side and low-side power transistors, and adjustable over-current protection.

Application Field

The M63993FP is specifically designed for use in motor drives, power conversion, motor control, and other applications where an integrated power management integrated circuit (PMIC) is necessary. Its wide voltage range and integrated features make it ideally suited for these applications. The M63993FP is also suitable for other applications such as lighting, heating, and air-conditioning controls, as well as renewable energy systems, monitoring and control systems, and power supplies. It is ideal for use in embedded systems due to its low-voltage operation, high-efficiency integrated driver core, POR circuit, and adjustable over-current protection. The M63993FP is also ideal for automotive applications due to its wide operating temperature range of -40°C to +105°C, robust thermal design, and adjustable deadtime and voltage-shift control.

Working Principle

The M63993FP is an integrated gate driver that is operated from an 8-bit microcontroller. It uses two separate power supplies, one for its logic circuits and the other for its gate driver core. The logic-level power supply is connected to the microcontroller’s power supply, while the gate driver-level power supply is connected to an external gate driver. The logic-level power supply also provides reset signals to the integrated gate driver. The logic signals provided by the microcontroller are used to control the driver circuit, which is responsible for driving the gate of the power transistor. The offset voltage between the gate of the power transistor and its source and drain is the driving voltage Vgs(x) = Vgs + Voffset and it typically ranges from 5V to 20V. The gate driver core of the M63993FP is designed to deliver a source current of 5A (max) and a drain current of 25A (max). The M63993FP also features adjustable over-current protection, adjustable voltage limit, and adjustable deadtime control. The adjustable deadtime control is used to optimize the simultaneous on/off switching of the power transistor, while the adjustable voltage limit prevents overvoltages on the power transistor\'s gate. The adjustable over-current protection ensures that the power transistor is not damaged by a sudden surge in current. The integrated power management integrated circuit (PMIC) also provides a power-on reset (POR) circuit to ensure that proper startup conditions are set.
