ADuM6132

GENERAL DESCRIPTION

The ADuM61321 is an isolated half-bridge gate driver that employs
Analog Devices’ iCoupler® technology to provide an isolated high­side 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.

difficulties associated with external supply configurations such
as a bootstrap circuitry.

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).

The maximum output current is the maximum isolated supply current that the ADuM6132 can provide. This current supports external loads as well as the needs of

the ADuM6132 Channel A output circuitry. This is achieved via external connection of V
external loads is the ADuM6132 output current I

Duration less than 1 second. Average output current must conform to the limit shown under the Absolute Maximum Ratings.

4

The minimum pulse width is the shortest pulse width at which the specified pulse width distortion is guaranteed. Operation below the minimum pulse width is not

recommended.

5

The maximum switching frequency is the maximum signal frequency at which the specified timing parameters are guaranteed. Operation beyond the maximum

frequency is not recommended since high switching rates can cause droop in the output supply voltage.

6

t

propagation delay is measured from the 50% level of the falling edge of the VIx signal to the 50% level of the falling edge of the VOx signal. t

PHL

measured from the 50% level of the rising edge of the VIx signal to the 50% level of the rising edge of the VOx signal.

7

“Channel-to-channel matching, rising or falling matching edge polarity” is the magnitude of the propagation delay difference between two channels of the same part

when both inputs are either both rising or falling edges. The loads on each channel are equal.

8

“Channel-to-channel matching, rising vs. falling opposite edge polarity” is the magnitude of the propagation delay difference between two channels of the same part

when one input is a rising edge and one input is a falling edge. The loads on each channel are equal.

9

Part-to-part matching is the magnitude of the propagation delay difference between the same channels of two different parts. This includes rising vs. rising, falling vs.

falling, or rising vs. falling edges. The supply voltages, temperatures, and loads of each part are equal.
