ADUM5230

Data Sheet Isolated Half-Bridge Driver with Integrated High-Side Supply ADuM5230 FEATURES Integrated, isolated high-side supply 150 mW of secondary side power Isolated high-side and low-side outputs 100 mA output source current, 300 mA output sink current High common-mode transient immunity: >25 kV/μs High temperature operation: 105°C Adjustable power level Wide body, 16-lead SOIC package Safety and regulatory approvals UL recognition: 2500 V rms for 1 minute per UL1577 Qualified for automotive applications APPLICATIONS MOSFET/IGBT gate drives Automotive Motor drives Power supplies 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 bootstrap circuitry. This highside isolated supply powers not only the ADuM5230 high-side output but also any external buffer circuitry used with the ADuM5230.
