Power Management Integrated circuit (PMIC) are controllers that manage several power supply circuits within an electronic system. PMIC offer significant improvements in power control efficiency and accuracy when compared to discrete, manual component-based solutions. They are used across a wide range of applications including industrial, consumer, medical, automotive, and computer products. In modern products, the use of PMICs is commonplace, resulting in a corresponding increase in demand for varieties of PMICs with different features and capabilities. PMICs are designed to manage the system’s power consuming components, like processors, displays, audio amplifiers and other peripherals, by distributing the power across multiple levels and segments.

One essential component of a PMIC is the gate driver. Gate drivers provide a level of protection between the PMIC and high-powered components, and their purpose is to operate switches and transistors, allowing the PMIC to control the power supply to the components it manages. Gate drivers typically operate by turning off and on the switches that control the power flow in a power supply circuit, and they can also open and close the transistors that govern the circuit.

The FAN7389M is a high speed gate driver designed to drive MOSFETs and IGBTs. The FAN7389M takes a single input voltage between 4.5V and 18V and provides two controlled outputs that can drive MOSFETs and IGBTs with supply voltage up to 600V and currents over 6A. The FAN7389M features high speed switching operations up to 500 kHz with rise and fall times of 10 ns and 8 ns respectively, allowing for high efficiency power supply designs. The FAN7389M is also equipped with a built-in self-protection feature that shuts down the outputs when too much current is passed through them, preventing them from overheating and protecting the device from damage.

The FAN7389M is suited for applications such as motor drives, power supplies, lighting, energy conversion, and solar micro-inverters. The FAN7389M is also used in industrial motor applications such as motor controllers, industrial motor drives, and machine tools. The device is also well-suited for renewable energy applications such as solar and wind power, as well as PWM battery charger applications. Its wide input voltage range and low output saturation level make it suitable for automotive applications such as DC/DC converters, battery management systems, and powertrain control systems.

In summary, the FAN7389M is a high-performance, high-efficiency gate driver designed to enable reliable, robust, and cost-effective designs for a number of applications. With its high-speed switching, wide input voltage range, low output saturation level, and self-protection feature, the FAN7389M is an excellent choice for power management applications.
