The NCV5701A are advanced single-channel high-side and low-side switched mode gate drivers. They provide a high level of integration, enabling simple and cost-efficient implementations of high-side plus low-side power switches.

The NCV5701A offer a number of features, including adjustable dead time with integrated logic and open-collector diagnostic output, making the driver appropriate for a wide range of applications.

The NCV5701A operates from a 4.5V to 18V supply voltage and is suitable for driving N-channel MOSFET and IGBT devices up to 40V.

Application Field

The NCV5701A supports a wide range of applications, from low current gate drive requirements of low-side switches and H-bridge configurations to the high current gate drive requirements of resonant converters and positive displacement compressors.

The drivers can also be used in step down, step up and DC-DC converter applications. In addition, the NCV5701A is designed for automotive and commercial applications like general-purpose relays and motor drives.

Working Principle

The working principle of the NCV5701A is based on switched-mode operation, which allows the outputs to switch rapidly with low losses. This is achieved by switching the top and bottom half of the gate driver on or off at a certain frequency, closing or opening the switch or gate alternatively.

The driver features an adjustable dead time with integrated logic, providing superior protection of the power MOSFETs by avoiding cross conduction. The output current offered by the driver is sufficient to operate N-channel MOSFETs and IGBTs with minimum rise and fall times.

The NCV5701A also offers an Open-Drain Diagnostic Output pin, which can be used to indicate the status of the driver’s outputs, allowing easy monitoring of the gate driving circuit. The driver also incorporates short circuit protection, over temperature shutdown and under voltage lock-out.

Overall, the NCV5701A provides the necessary support for cost-effective implementation of high-side plus low-side power switches.
