Isolated, Precision Half-Bridge Driver, 0.1 A Output ADuM1233 Data Sheet FEATURES GENERAL DESCRIPTION Isolated high-side and low-side outputs High side or low side relative to input: ±700 VPEAK High-side/low-side differential: 700 VPEAK 0.1 A peak output current High frequency operation: 5 MHz maximum High common-mode transient immunity: >75 kV/µs High temperature operation: 105°C Wide body, 16-lead SOIC Safety and regulatory approvals UL recognition 2500 V rms for 1 minute per UL 1577 VDE certificate of conformity DIN V VDE V 0884-10 (VDE V 0884-10): 2006-12 VIORM = 560 V peak The ADuM12331 is an isolated, half-bridge gate driver that uses the Analog Devices, Inc., iCoupler® 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 that use 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. APPLICATIONS Isolated IGBT/MOSFET gate drives Plasma displays Industrial inverters Switching power supplies 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.

C | Page 8 of 12 Data Sheet ADuM1233 APPLICATIONS INFORMATION The transient magnitude of the sinusoidal component is given by VCM, linear = (ΔV/Δt) t where ΔV/Δt is the slope of the transient shown in Figure 12 and Figure 13. The transient of the linear component is given by dVCM/dt = ΔV/Δt The ability of the ADuM1233 to operate correctly in the presence of linear transients is characterized by the data in Figure 9. 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 6 because the transient immunity values obtained in Table 6 use measured data and apply allowances for measurement error and margin. 400 The ability of the ADuM1233 to operate correctly in the presence of sinusoidal transients is characterized by the data in Figure 10 and Figure 11. The data is based on design simulation and is the maximum sinusoidal transient magnitude (2πf V0) that the ADuM1233 can tolerate without an operational error. Values for immunity against sinusoidal transients are not included in Table 6 because measurements to obtain such values have not been possible. 300 250 BEST-CASE PROCESS VARIATION 200 150 100 50 BEST-CASE PROCESS VARIATION 300 WORST-CASE PROCESS VARIATION 0 0 250 750 1000 1250 FREQUENCY (MHz) 200 Figure 10.
