The UC2708NG4 Integrated Gate Driver from Texas Instruments is part of the Company’s power management integrated circuit (PMIC) gate driver family. This PMIC gate driver is designed to provide robust and reliable gate drive signals for N-channel MOSFETs and IGBTs. It is specifically optimized for applications that require high-current gate drive.

The UC2708NG4 provides high-current gate drive for N-channel MOSFETs and IGBTs in two different configurations of two-outputs or combinations of one- and two-outputs. It offers a high level of integration, low internal impedance, and minimal external components, which cuts down the size, components and cost of a complete gate drive system. Its protection features, including overcurrent and overtemperature protection, reduce design complexity and minimize external components.

The UC2708NG4 offers a wide range of features including adjustable totem-pole outputs, adjustable slew rates, adjustable delay times, fault diagnostics and soft-start functionality. As such, it is an ideal solution for low side and high side power switching applications, such as motor control, DC/DC converters, appliance controls and general purpose power switching.

The UC2708NG4 works on the principle of switching the control signal from the output supply rail to the input device. This switching is done by driving a transistor to reduce the current through the device, thus controlling its voltage. The output of the transistor is then passed to the gate of the MOSFET or IGBT, resulting in a change in the output of the device.

The UC2708NG4 gate driver includes shutdown, enable and fault status signals that allow the system to monitor the state of the gate signals. This gate driver also has the ability to control the threshold voltage, rise times and fall times of the output signal.

The UC2708NG4 ICs are available in various package types such as DSOF6, TO-220, TO-218 and QFN. These ICs are rated for operation from -40 degrees Celsius to 125 degrees Celsius and can be used in automotive and industrial applications. They are also available in voltage ratings of 9V to 30V.

The UC2708NG4 from Texas Instruments is a powerful and reliable gate driver for N-channel MOSFETs and IGBTs. It offers high levels of integration, low internal impedance, and minimal external components. Its wide range of features and adjustable threshold voltage, rise time and fall time make it an ideal choice for low side and high side power switching applications.
