The ADuM3150 is a 6-channel SPIsolator™digital isolator optimized for isolated serial peripheral interfaces (SPIs). Based on the Analog Devices, Inc.,iCoupler®chip scale transformer technology, the low propagation delay in the CLK, MO/SI, MI/SO, andSSSPI bus signals supports SPI clock rates of up to 17 MHz. These channels operate with 14 ns propagation delay and 1 ns jitter to optimize timing for SPI.The ADuM3150 isolator also provides two additional independent low data rate isolation channels, one channel in each direction. Data in the slow channels is sampled and serialized for a 250 kbps data rate with 2.5 μs of jitter.The ADuM3150 supports a delay clock output on the master side of the device. This output can be used with an additional clocked port on the master to support 40 MHz clock performance.

The ADuM4121/ADuM4121-1 are 2 A isolated, single-channel drivers that employ Analog Devices, Inc.’siCoupler®technology to provide precision isolation. The ADuM4121/ADuM4121-1 provide 5 kV rms isolation in the wide-body, 8-lead SOIC package. Combining high speed CMOS and monolithic transformer technology, these isolation components provide outstanding performance characteristics superior to alternatives such as the combination of pulse transformers and gate drivers.The ADuM4121/ADuM4121-1 operate with an input supply ranging from 2.5 V to 6.5 V, providing compatibility with lower voltage systems. In comparison to gate drivers that employ high voltage level translation methodologies, the ADuM4121/ ADuM4121-1 offer the benefit of true, galvanic isolation between the input and the output.The ADuM4121/ADuM4121-1 include an internal Miller clamp that activates at 2 V on the falling edge of the gate drive output, supplying the driven gate with a lower impedance path to reduce the chance of Miller capacitance induced turn on.Options exists to allow the thermal shutdown to be enabled or disabled.

The ADuM4122 is an isolated, single device, dual output driver that usesiCoupler®technology to provide precision isolation. The ADuM4122 provides 5 kV rms isolation in the wide-body, 8-lead SOIC package. These isolation components combine high speed complementary metal-oxide semiconductor (CMOS) and monolithic transformer technology to provide performance characteristics superior to alternatives (such as a combination of pulse transformers and gate drivers).The ADuM4122 operates with an input supply voltage range from 3.3 V to 6.5 V, providing compatibility with lower voltage systems. Unlike gate drivers that employ high voltage level translation methodologies, the ADuM4122 offers true galvanic isolation between the input and the output regions.The ADuM4122 includes two output pins that facilitate slew rate control of two output drive strengths. The VOUTpin follows the logic of the VIN+pin, while the boosting output, VOUT_SRC, can be toggled to follow the VIN+pin or to go high-Z. The toggling of the slew rate is controlled by the primary side. Slew rate control can allow for electromagnetic interference (EMI) mitigation and voltage overshoot control.An internal thermal shutdown sets outputs low if internal temperatures on the ADuM4122 exceed the thermal shutdown temperature.As a result, the ADuM4122 provides reliable control over the switching characteristics of insulated gate bipolar transistor (IGBT) and metal-oxide semiconductor field effect transistor (MOSFET) configurations over a wide range of switching voltages, allowing for simple slew rate control.ApplicationsSwitching power suppliesIsolated IGBT and MOSFET gate driversIndustrial inverters
