Isolated Half-Bridge Driver with Integrated High-Side Supply ADuM5230

GENERAL DESCRIPTION

The ADuM52301 is an isolated half-bridge gate driver that employs Analog Devices, Inc.,i Coupler® 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.

APPLICATIONS

MOSFET/IGBT gate drive Plasma display modules Motor drives

Power supplies Solar panel inverters

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 VP 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 VP.

1 Short-circuit duration is less than 1 sec. Average output current must conform to the limit shown under the Absolute Maximum Ratings section.

2 The minimum pulse width is the shortest pulse width at whichthe 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.

3The 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.

4tPHL 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. tPLH 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.

5In 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.

7In 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.

8In 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.
