Isolators are electronic devices used to transfer signals from one side to the other through electrical isolation. This means isolators provide one mode of passing signals without any electrical connection between the two sides. Isolators can operate as isolators, as current transfer devices, as amplifiers, and as converters. Isolators are widely used in industrial processes, communication systems, medical equipment, and some consumer products.

Gate drivers are used to provide high current and high voltage inputs to drive electromechanical switches such as MOSFETs and IGBTs for power conversion applications. Gate drivers are essentially isolation devices that use circuit-based logic to switch the gate connections of an isolated logic device. Gate drivers are commonly employed in circuits to ensure that the gate of a semiconductor switch does not go high or low too quickly, or at too low a voltage, in order to ensure its long-term stability and reliability.

The ADUM3221BRZ-RL7 isolator is a ultra-small, low-growth, three-level gate driver device for high-temperature operation. The device provides full drive and return voltage isolation of up to 500 volts, making it suitable for both high-voltage and low-voltage power switch control circuits. The device supports both a low-voltage (5–15 V) and a high-voltage (20–48 V) gate driver in a single device, allowing for flexible power switch circuit designs.

The working principle of the ADUM3221BRZ-RL7 is quite simple. When the driver provides a full high or low output pulse to the gate, the internal circuitry in the device ensures that the gate is driven up or down quickly, with enough voltage to ensure proper conduction through the power switch. The device also provides the proper gate return voltage required for the accurate operation of the power switch. Additionally, the device is designed to protect against inadvertent use of a low-voltage driver on a high-voltage switch, preventing gate voltage levels from inadvertently exceeding the allowable voltage of the switch.

The ADUM3221BRZ-RL7 is an excellent choice for applications such as AC/DC and DC/DC conversion, power over Ethernet (PoE) applications, high-voltage motor control, and motor driver circuits. The device can also be used for low voltage linear and switching power supplies, energy storage systems, and other industrial automation applications. This device ensures that the power switches are accurately and reliably driven, and that the circuit’s isolation is maintained.
