NCV7462DQ0R2G series ICs are power line transceivers built with a partial galvanic isolation of up to 5 kVrms. These devices provide an interface in between low voltage control logic and power line in electrically noisy environments. With their unique SmartDiagnostics technology, these ICs are able to gauge the quality of their environment. They are suited for automotive applications such as electric vehicle (EV) chargers, lighting systems, and onboard diagnostics.

Application fields

NCV7462DQ0R2G series ICs are a great choice for electrically noisy power line applications. They can be used in various areas such as:

• Automotive: EV chargers, lighting systems, onboard diagnostics.
• Industrial motor control.
• Industrial automation.
• Automatic meter readers.
• Protection relays.

The devices are also ideal for connecting data points between high and low voltage systems. They are well-suited for applications with mandated galvanic isolation requirements, such as Transportation Vehicle battery equipment portable charger, handheld tools, laptop chargers, and portable control equipment.

Working Principle

NCV7462DQ0R2G series ICs use a differential line transceiver with a shutdown pin to enable partial galvanic isolation up to 5 kVrms. It works by injecting a differential signal between the input and output lines, while ensuring a high level of common mode noise immunity over the entire DC to 100 MHz operational frequency range. The full-duplex communication interface supports speeds up to 2 Mbps and can adapt to varying cable lengths.

These devices have built-in SmartDiagnostics technology which allows them to detect cable length and the environment in which they are operating. It also monitors power line quality for conditions such as shorting, low voltage, high voltage and current, and overvoltage. The ICs can then shut off if any of these conditions occurs, protecting them from damage.

Overall, NCV7462DQ0R2G series ICs are a great choice for applications requiring partial galvanic isolation between low voltage logic and a power line. Their SmartDiagnostics technology makes them reliable, versatile and easy to use. The built-in monitoring capabilities help protect these devices from damage, ensuring safe and efficient operation in electrically noisy environments.
