GENERAL DESCRIPTION
The ADuM52301 is an isolated half-bridge gate driver that employs Analog Devices, Inc., iCoupler® technology to provide independent and isolated high-side and low-side outputs. Combining CMOS and microtransformer technologies, this isolation component contains an integrated dc-to-dc converter providing an isolated high-side supply. This eliminates the cost, space, and performance difficulties associated with external supply configurations such as a bootstrap circuitry. This high­side isolated supply powers not only the ADuM5230 high-side output but also any external buffer circuitry used with the ADuM5230.
In comparison to gate drivers employing high voltage level translation methodologies, the ADuM5230 offers the benefit of true, galvanic isolation between the input and each output. Each output can operate up to ±700 V
P
relative to the input, thereby supporting low-side switching to negative voltages. The differential voltage between the high-side and low-side may be as high as 700 V
P

The minimum pulse width is the shortest pulse width at which the specified timing parameters are guaranteed. Operation below the minimum pulse width is strongly
discouraged because in some instances pulse stretching to 1 μs may occur.
3
The maximum switching frequency is the maximum signal frequency at which the specified timing and power conversion parameters are guaranteed. Operation
above the maximum frequency is strongly discouraged.

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
PLH
propagation delay is
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.

In channel-to-channel matching, the 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.
6
In channel-to-channel matching, the 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.
7
In part-to-part matching, the rising or falling edges is the magnitude of the propagation delay difference between the same channels of two different parts when the
inputs are either both rising or falling edges. The supply voltages, temperatures, and loads of each part are equal.
8
In part-to-part matching, the rising vs. falling edges is the magnitude of the propagation delay difference between the same channels of two different parts when one
input is a rising edge and the other input is a falling edge. The supply voltages, temperatures, and loads of each part are equal.
