Isolator Gate Drivers are the interface between power signals and an external MOSFET or Bridge architecture circuit. The technology types are capacitive coupling, magnetic coupling, and optical coupling with 1, 2, or 4 channels. The voltage isolation ranges from 1000Vrms to 7500Vrms and the propagation delay ranges from 30ns to 5ms.
Technology: Describes the basic building-block technology used to construct the device, determining its overall behavior.
Number of Channels: Indicates the number of separate isolation channels the device is equipped with.
Voltage - Isolation: The maximum voltage difference that can be observed across the device’s isolation barrier before breakdown occurs and isolation is lost.
Common Mode Transient Immunity (Min): Characterizes a rate of voltage change across a device’s isolation barrier that if exceeded may be expected to cause errors in the signal(s) being transmitted through a device.
Propagation Delay tpLH / tpHL (Max): Characterizes signal transmission delays introduces by a device, for both low->high and high->low signal transitions.
Pulse Width Distortion (Max): Characterizes the maximum difference between high-to-low and low-to-high progagation delays exhibited by a part.
Rise / Fall Time (Typ): Characterizes the amount of time required for a device output to transition from low to high/high to low states, which are commonly defined as 10% and 90% of the supply voltage that powers the output being measured.
Current - Output High, Low: Indicates the device’s maximum current handling capability while sourcing current to a load (High) or sinking current from a load (Low).
Current - Peak Output: The absolute maximum current that a device is capable of supplying to an attached load on a transient basis.
Voltage - Forward (Vf) (Typ): Characterizes the device’s forward voltage drop across its internal diodes while in an Off state.
Current - DC Forward (If) (Max): Characterizes the device’s forward current through its internal diodes while in an ‘On’ state.
Voltage - Output Supply: The maximum voltage the device can provide on the output end of its isolation barrier, to downstream circuitry.
Operating Temperature: Recommended operating temperature, typically given in a range or as a maximum. Exceeding these temperatures may affect performance or damage the device and other system components.
Mounting Type: Indicates how the device is attached.
Package / Case: Indicates the type of protective case used on an electronic component to allow easy handling, installation, and protection. This selection was determined to be the closest industry standard applicable to the supplier device packaging. Typically it is best to check the actual dimensions from the datasheet rather than depend on this terminology when designing your circuit.
Supplier Device Package: This is what the manufacturer calls the package of this device. They are manufacturer specific. It is typically best to use the actual dimensions from the datasheets rather than to go by this terminology when designing your circuit.
Approval Agency: An indication that the product meets the minimum safety standards of an approving agency. These agencies are either government entities or private third-party labs that protect consumer safety.
