ADuM4122 Adjustable Slew Rate, Single Isolated Gate Driver

ADuM4122 Adjustable Slew Rate, Single Isolated Gate Driver

Analog Devices' gate driver, 3 A short-circuit (less than 3 Ω) is ideal for applications such as switching power supplies

Analog Devices' ADuM4122 is an isolated, single device, dual output driver that uses iCoupler® technology to provide precision isolation and provides 5 kVRMS 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 features two output pins that facilitate slew rate control of two output drive strengths. The VOUT pin 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.

The gate drivers provide 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.
