GENERAL DESCRIPTION
The ADuM12331 is an isolated, half-bridge gate driver that employs the Analog Devices, Inc. iCoupler(R) technology to provide independent and isolated high-side and low-side outputs. Combining high speed CMOS and monolithic transformer technology, this isolation component provides outstanding performance characteristics superior to optocoupler-based solutions. By avoiding the use of LEDs and photodiodes, this iCoupler gate drive device is able to provide precision timing characteristics not possible with optocouplers. Furthermore, the reliability and performance stability problems associated with optocoupler LEDs are avoided. In comparison to gate drivers employing high voltage level translation methodologies, the ADuM1233 offers the benefit of true, galvanic isolation between the input and each output. Each output can be operated up to 700 VPEAK relative to the input, thereby supporting low-side switching to negative voltages. The differential voltage between the high side and low side can be as high as 700 VPEAK. As a result, the ADuM1233 provides reliable control over the switching characteristics of IGBT/MOSFET configurations over a wide range of positive or negative switching voltages.

ADuM1233 APPLICATION NOTES
COMMON-MODE TRANSIENT IMMUNITY
In general, common-mode transients consist of linear and sinusoidal components. The linear component of a commonmode transient is given by VCM, linear = (V/t) t where V/t is the slope of the transient shown in Figure 11 and Figure 12. The transient of the linear component is given by dVCM/dt = V/t The ability of the ADuM1233 to operate correctly in the presence of linear transients is characterized by the data in Figure 8. The data is based on design simulation and is the maximum linear transient magnitude that the ADuM1233 can tolerate without an operational error. This data shows a higher level of robustness than what is listed in Table 5 because the transient immunity values obtained in Table 5 use measured data and apply allowances for measurement error and margin.
400 350
TRANSIENT IMMUNITY (kV/s)
The transient magnitude of the sinusoidal component is given by dVCM/dt = 2f V0. The ability of the ADuM1233 to operate correctly in the presence of sinusoidal transients is characterized by the data in Figure 9 and Figure 10. The data is based on design simulation and is the maximum sinusoidal transient magnitude (2f V0) that the ADuM1233 can tolerate without an operational error. Values for immunity against sinusoidal transients are not included in Table 5 because measurements to obtain such values have not been possible.
