common mode transient immunity (CMTI)

Common Mode Transient Immunity (CMTI) is a characteristic value for the immunity of isolated gate drivers to common mode pulses.

Common Mode Transient Immunity (CMTI) is a characteristic value of gate drivers that must be considered when operating at higher switching frequencies or at maximum permissible rise times and fall times. It is defined as the maximum tolerable rise time or fall time of the common mode voltage applied between two isolated circuits. The unit is usually expressed in kilovolts per microsecond (kV/┬Ás). A high CMTI value means that the two isolated circuits, both on the transmitter and receiver side, are operating fault-free within the given specifications.
