Isolator Gate Drivers are types of components used to provide isolated electrical signal between two systems. Put simply, they provide two sets of electrical signals, one set from the source system and one set to the destination system. This ensures the isolation of the two systems while providing a common electrical connection.

The ACNW3430-000E Isolator Gate Driver from Linear Technology is a self-contained device in the ISOW86 family of Isolators. It is a low-cost, high performance, low-voltage option for unipolar and bipolar motor drive applications. This family of gate drivers includes three isolators – the ACNW3430-000E, the ACNW3430-000S, and the ACNW3430-001 – which offer the highest voltage range, highest isolation voltage, and a low voltage tape-and-reel package.

The ACNW3430-000E has a wide range of applications, including unipolar or bipolar motor drives, solenoid and valve control, and any other application requiring isolation of two different systems. The device provides 2kV of isolation with an input to output common mode differential voltage of 1.5kV. The device also has very low power consumption, and can operate from 4.5V to 12V, which makes it suitable for low voltage applications. These features make the ACNW3430-000E an ideal solution for any application requiring isolation of two systems.

The working principle of the ACNW3430-000E is relatively simple: it uses a combination of capacitors, transistors, and diodes to provide isolation between the input and output circuits. The input side of the device has an isolation transformer that provides isolation between the input and output. A current control loop is used to limit the input current, which is then used to provide the output current. The output comprises of a pair of N-channel FETs that switch the output voltage to the appropriate level.

The ACNW3430-000E can be used in an isolated power supply configuration when used in conjunction with other Linear Technology components such as the LT3989 and LT3911. This provides an integrated solution for powering and controlling isolated circuits. When used with this setup, the ACNW3430-000E can provide up to 2A of output current, as well as up to 20V of output voltage.

The ACNW3430-000E provides a reliable and cost-effective solution for any application where the investigation of two different systems is required. Its low power consumption, wide input/output voltage range, and high isolation level make it suitable for a variety of applications ranging from unipolar and bipolar motor drives to solenoid and valve control.
