Wide-body, 8-lead SOIC_IC

The ADuM4122 is an isolated, single device, dual output driverthat uses iCoupler® technology to provide precision isolation.The ADuM4122 provides 5 kV rms isolation in the wide-body,8-lead SOIC package. These isolation components combinehigh speed complementary metal-oxide semiconductor (CMOS)and monolithic transformer technology to provide performancecharacteristics superior to alternatives (such as a combination ofpulse transformers and gate drivers).

The ADuM4122 operates with an input supply voltage rangefrom 3.3 V to 6.5 V, providing compatibility with lower voltagesystems. Unlike gate drivers that employ high voltage leveltranslation methodologies, the ADuM4122 offers true galvanicisolation between the input and the output regions.

The ADuM4122 includes two output pins that facilitate slewrate control of two output drive strengths. The V_OUT pin followsthe logic of the V_IN+ pin, while the boosting output, V_{OUT_SRC},can be toggled to follow the V_IN+ pin or to go high-Z. Thetoggling of the slew rate is controlled by the primary side. Slewrate control can allow for electromagnetic interference (EMI)mitigation and voltage overshoot control.

An internal thermal shutdown sets outputs low if internaltemperatures on the ADuM4122 exceed the thermal shutdowntemperature.

As a result, the ADuM4122 provides reliable control over theswitching characteristics of insulated gate bipolar transistor (IGBT)and metal-oxide semiconductor field effect transistor (MOSFET)configurations over a wide range of switching voltages, allowingfor simple slew rate control.
