The ADUM6132ARWZ 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 275mW high-side supply. This supply, provided by an internal isolated DC-to-DC converter, powers not only the driver high-side output but also any external buffer circuitry that is commonly used with the driver. This functionality eliminates the cost, space and performance issues associated with external supply configurations such as a bootstrap circuit. The architecture of the driver isolates the high-side channel and the high-side power from the control and low-side 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. In comparison to gate drivers that employ high voltage level translation methodologies, the driver offers the benefit of true, galvanic isolation.
