GENERAL DESCRIPTION
The ADuM6132¹ is an isolated half-bridge gate driver that employs
Analog Devices’ iCoupler® technology to provide an isolated high-
side driver with an integrated 300 mW high-side supply. This
supply, provided by an internal isolated DC/DC converter powers
not only the ADuM6132’s high-side output but also any external
buffer circuitry that would commonly be used with the
ADuM6132. This eliminates the cost, space, and performance
difficulties associated with external supply configurations such
as a bootstrap circuitry. The architecture isolates the high side
channel and high side power from the control and low side
interface circuitry. Care has been taken to ensure close matching
between the high and low side driver timing characteristics,
reduces the need for dead time margin.
In comparison to gate drivers employing high voltage level
translation methodologies, the ADuM6132 offers the benefit of
true, galvanic isolation. The differential voltage between high and
low side channels can be as high as 1131V in some configurations
(see Table 7).
