The ADuM3220/ADuM32211 are isolated, 4A dual-channel gate drivers based on the Analog Devices, Inc., iCoupler?technology. Combining high speed CMOS and monolithic transformer technology, these isolation components provide outstandingperformance characteristics superior to the alternatives, such as the combination of pulse transformers and gate drivers.The ADuM3220/ADuM3221 provide digital isolation in two independent isolation channels. They have a maximum propagationdelay of 60 ns and 5 ns channel-to-channel matching. In comparison to gate drivers that employ high voltage level translationmethodologies, the ADuM3220/ADuM3221 offer the benefit of true, galvanic isolation between the input and each output,enabling voltage translation across the isolation barrier. The ADuM3220 has shoot-through protection logic, which preventsboth outputs from being on at the same time, whereas the ADuM3221 allows both outputs to be on at the same time. Both partsoffer a default output low characteristic as required for gate drive applications.The ADuM3220/ADuM3221 operate with an input supply voltage ranging from 3.0 V to 5.5 V, providing compatibility with lowervoltage systems. The outputs of the ADuM3220A/ADuM3221A can be operated at supply voltages from 4.5 V to 18 V. The outputs ofthe ADuM3220B/ADuM3221B can be operated at supply voltages from 7.6 V to 18 V.The junction temperature of the ADuM3220/ADuM3221 is specified from ?40?C to +125?C.Applications Isolated synchronous dc-to-dc converters MOSFET/IGBT gate drivers

The ADuM4070 is a regulated DC/DC isolated power supply controller with an internal MOSFET driver. The DC/DC controller has an internal isolated PWM feedback from the secondary side based on the?iCoupler? chip scale transformer technology and complete loop compensation. This eliminates the need to use an optocoupler for feedback and compensates the loop for stability.The ADuM4070 isolator provides a more stable output voltage and higher efficiency compared to unregulated isolated DC/DC jpower supplies. The fully integrated feedback and loop compensation in a wide-body SOIC package provide a smaller form factor and 8.3 mm creepage distance solution. The regulated feedback provides a relatively flat efficiency curve over the full output power range. The ADuM3070 enables a DC/DC converter with a 3.3 V to 24 V isolated output voltage range from either a 5.0 V or a 3.3 V input voltage, with an output power of up to 2.5 W.Applications Power supply startup bias and gate drives Isolated sensor interfaces Process controls

The ADuM4146 is a single-channel gate driver specifically optimized for driving silicon carbide (SiC), metal-oxide semiconductor field effect transistors (MOSFETs). Analog Devices, Inc., iCoupler? technology provides isolation between the input signal and the output gate drive.The ADuM4146 includes a Miller clamp to provide robust SiC turn off with a single-rail supply when the gate voltage drops to less than 2 V. Operation with unipolar or bipolar secondary supplies is possible with or without the Miller clamp operation.The Analog Devices chip scale transformers also provide isolated communication of control information between the high voltage and low voltage domains of the chip. Information on the status of the chip can be read back from dedicated outputs. Control of resetting the device after a fault on the secondary side is performed on the primary side of the device.Integrated onto the ADuM4146 is a desaturation detection circuit that provides protection against high voltage short-circuit SiC operation. The desaturation protection contains noise reducing features, such as a 300 ns masking time after a switching event to mask voltage spikes due to initial turn on (see Figure 17 in the data sheet). An optional internal 500 ?A current source allows low device count, and the internal blanking switch allows the addition of an external current source if more noise immunity is needed.The secondary undervoltage lockout (UVLO) is set to 14.5 V (typical) for Grade A and is set to 11.5 V (typical) for Grade B and Grade C with common SiC and insulated gate bipolar transistor (IGBT) levels taken into consideration.
