It is designed to drive power transistors up to 5-MHz with best-in-class propagation delay and pulse-width distortion. The input side is isolated from the two output drivers by a 2.5-kVRMS isolation barrier, with 100-V/ns minimum common-mode transient immunity (CMTI). Internal functional isolation between the two secondary side drivers allows working voltage up to 700-VDC. This driver can be configured as two low-side, two high-side, or a half-...
