GENERAL DESCRIPTION
The ADUM1230 1 is an isolated half-bridge gate driver that employs Analog Devices' 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 ADUM1230 offers the benefit of true, galvanic isolation between the input and each output. Each output may be operated up to 700 VP 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 VP. As a result, the ADUM1230 provides reliable control over the switching characteristics of IGBT/MOSFET configurations over a wide range of positive or negative switching voltages.

ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although this product features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.

ADUM1230 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 ADUM1230's ability 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 ADUM1230 can tolerate without an operational error. This data shows a higher level of robustness than what is shown in Table 5 because the transient immunity values obtained in Table 5 use measured data and apply allowances for measurement error and margin.
300
The transient magnitude of the sinusoidal component is given by dVCM/dt = 2f V0 The ADUM1230's ability 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 ADUM1230 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.

TYPICAL APPLICATION USAGE
The ADUM1230 is intended for driving low gate capacitance transistors (200 pF typically). Most high voltage applications involve larger transistors than this. To accommodate these situations, users can choose either a gate driver with a stronger output stage or the buffer configuration with the ADUM1230, as shown in Figure 14. In many cases, the buffer configuration is the less expensive of the two options and provides the greatest amount of design flexibility. The precise buffer/high voltage transistor combination can be selected to fit the application's needs.
