ADUM5230 Datasheet | Analog Devices

FEATURES Integrated, isolated high-side supply 150 m W of secondary side power Isolated high-side and low-side outputs 100 m A output source current, 300 m A output sink current High mon-mode transient immunity: >25 k V/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 ADu M52301 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. bining CMOS and microtransformer technologies, this isolation ponent 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 ADu M5230 high-side output but also any external buffer circuitry used with the ADu M5230.

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 Protected by U.S. Patents 5,952,849; 6,873,065; 6,903,578; 7,075,329; other pending patents. Rev.
