Overview
The ADUM5230WARWZ from Analog Devices Inc. is an isolated half-bridge gate driver that utilizes Analog Devices' iCoupler® technology. This component provides independent and isolated high-side and low-side outputs, making it ideal for applications requiring galvanic isolation. The ADUM5230 integrates a dc-to-dc converter, which supplies the high-side output and any external buffer circuitry, eliminating the need for external bootstrap circuitry. This design ensures true galvanic isolation between the input and each output, supporting differential voltages up to ±700 V.
