Isolated Half-Bridge Gate Driver with Integrated Isolated High-Side Supply ADuM6132 Data Sheet FEATURES GENERAL DESCRIPTION isoPower integrated isolated high-side supply 275 mW isolated dc-to-dc converter 200 mA output sink current, 200 mA output source current High common-mode transient immunity: >50 kV/µs Wide-body 16-lead SOIC package Safety and regulatory approvals UL recognition 3750 V rms for 1 minute per UL 1577 CSA Component Acceptance Notice #5A CSA/IEC 60950-1, 400 V rms VDE certificate of conformity (pending) DIN V VDE V 0884-10 (VDE V 0884-10):2006-12 VIORM = 560 V peak The ADuM61321 is an isolated half-bridge gate driver that employs the Analog Devices, Inc., iCoupler® technology to provide an isolated high-side driver with an integrated 275 mW high-side supply. This supply, provided by an internal isolated dc-to-dc converter, powers not only the ADuM6132 high-side output but also any external buffer circuitry that is commonly used with the ADuM6132. This functionality eliminates the cost, space, and performance issues associated with external supply configurations such as a bootstrap circuit. The architecture of the ADuM6132 isolates the high-side channel and the high-side power from the control and lowside interface circuitry. Care has been taken to ensure close matching between the high-side and low-side driver timing characteristics to reduce the need for a dead time margin. APPLICATIONS In comparison to gate drivers that employ high voltage level translation methodologies, the ADuM6132 offers the benefit of true, galvanic isolation. The differential voltage between high-side and low-side channels can be as high as 800 V with good insulation lifetime (see Table 12). MOSFET/IGBT gate drivers Motor drives Solar panel inverters Power supplies isoPower® uses high frequency switching elements to transfer power through its transformer. Special care must be taken during printed circuit board (PCB) layout to meet emissions standards. Refer to the AN-0971 Application Note for information about board layout considerations.

The preceding magnetic flux density values correspond to specific current magnitudes at given distances from the ADuM6132 transformers. Figure 20 expresses these allowable current magnitudes as a function of frequency for selected distances. As shown in Figure 20, the ADuM6132 is extremely immune and can be affected only by extremely large currents operated at high frequency and very close to the component. For example, at a magnetic field frequency of 1 MHz, a 0.5 kA current would need to be placed 5 mm away from the ADuM6132 to affect the operation of the component. Given the geometry of the receiving coil in the ADuM6132 and an imposed requirement that the induced voltage be at most 50% of the 0.5 V margin at the decoder, a maximum allowable magnetic flux density is calculated, as shown in Figure 19. MAXIMUM ALLOWABLE CURRENT (kA) 1000 β is the magnetic flux density (gauss). rn is the radius of the nth turn in the receiving coil (cm). N is the number of turns in the receiving coil.

Acceleration factors for several operating conditions are determined. These factors allow calculation of the time to failure at the actual working voltage. Table 12 summarizes the recommended peak working voltages for 50 years and 15 years of service life for various operating conditions evaluated by Analog Devices. In many cases, the approved working voltage is higher than the 50-year service life voltage. Operation at these high working voltages can lead to shortened insulation life in some cases. Any cross-insulation voltage waveform that does not conform to Figure 22 or Figure 23 should be treated as a bipolar ac waveform, and its peak voltage should be limited to the 50-year lifetime voltage value listed in Table 12. Note that the voltage shown in Figure 22 is sinusoidal for illustration purposes only. It is meant to represent any voltage waveform varying between 0 V and some limiting value. The limiting value can be positive or negative, but the voltage cannot cross 0 V. RATED PEAK VOLTAGE 07393-021 All insulation structures eventually break down when subjected to voltage stress over a sufficiently long period. The rate of insulation degradation depends on the characteristics of the voltage waveform applied across the insulation. In addition to the testing performed by the regulatory agencies, Analog Devices conducts an extensive set of evaluations to determine the lifetime of the insulation structure within the ADuM6132. 0V Figure 21. Bipolar AC Waveform RATED PEAK VOLTAGE 07393-022 INSULATION LIFETIME In the case of unipolar ac or dc voltage, the stress on the insulation is significantly lower, which allows operation at higher working voltages while still achieving a 50-year service life. The working voltages listed in Table 12 can be applied while maintaining the 50-year minimum lifetime, provided that the voltage conforms to either the unipolar ac or dc voltage cases. 0V The insulation lifetime of the ADuM6132 depends on the voltage waveform type imposed across the isolation barrier. The iCoupler insulation structure degrades at different rates depending on whether the waveform is bipolar ac, unipolar ac, or dc. Figure 21, Figure 22, and Figure 23 illustrate these different isolation voltage waveforms. Figure 22. Unipolar AC Waveform RATED PEAK VOLTAGE 07393-023 Note that in the presence of strong magnetic fields and high frequencies, any loops formed by PCB traces may induce sufficiently large error voltages to trigger the threshold of succeeding circuitry. Care should be taken in the layout of such traces to avoid this possibility. 0V Bipolar ac voltage is the most stringent environment. The goal of a 50-year operating lifetime under the bipolar ac condition determines the maximum working voltage recommended by Analog Devices. Figure 23. DC Waveform Table 12.
