Power Management Integrated Circuits (PMIC) are found in a variety of applications. From the microcontroller in your phone, the actuator in your car, to the communication system in an aircraft, PMICs provide the necessary power and communication to get these applications up and running. Gate Drivers are one type of PMIC that are responsible for driving the output of power transistors and FETs in order to switch them on and off.

The 2EDN7424FXTMA1 is a power MOSFET gate driver, designed to drive and control the high-side and low-side power MOSFET with high voltage and peak power. It is a synchronous buck pre-driver IC that operates with input voltages ranging from 4.5V to 17V and can drive up to 6A peak source and 10A peak sink current. This IC features a large input common-mode range and provides flexibility in system layout by not requiring a common-mode choke. Its fast switching performance of up to 1MHz enables fast transient response and, integrated bootstrap diodes prevent ground bounce.

Application fields for this IC a wide ranging. It can be used for low side and high side switching applications such as switched mode power supply, DC/DC converters, motor drives and gate drivers for power MOSFETs and IGBTs. The 2EDN7424FXTMA1 is also popular in automotive applications due to its robustness and well-suited design. It is suitable for automotive telecoms, displays, dashboard modules and other connected car systems.

The 2EDN7424FXTMA1 works on the basis of two MOSFETs which can be connected in series to form a voltage divider circuit. When the power supply is connected, one of the MOSFETs is driven and begins to conduct current. This action causes the output voltage of the IC to drop, driving the other MOSFET in the voltage divider circuit into conduction. This allows the device to switch rapidly in both directions, supplying power to its load.

The IC can be used with a wide range of gate voltages and features selectable slew rate and de-glitch filters including a programmable dead-time control, which can be used to minimize ringing and overshoot. The integrated protection features include overcurrent, thermal shutdown and under voltage lockouts to protect both the IC and the circuit where it is used. It also has a programmable current limit and a built in overtemperature warning.

The 2EDN7424FXTMA1 is a popular Gate Driver IC, thanks to its wide range of features and robust performance. Its flexibility and durability make it an ideal choice for many applications, especially automotive systems.
