Infineon – Dual-channel isolated EiceDRIVER™ family 2EDi

Infineon – Dual-channel isolated EiceDRIVER™ family 2EDi

Fast, robust, dual-channel, functional and reinforced isolated MOSFET gate driver ICs with accurate and stable timing
The EiceDRIVER™ 2EDi dual-channel isolated product family is designed with our Coreless Transformers CT isolation technology for robust operation in high performance noisy half-bridges. The devices support primary and secondary control of hard- and soft power switching topologies for best power conversion efficiency.

Features
– Fast power switching with accurate timing
– Available with 4 A/8 A and 1 A/2 A source/sink currents
– Propagation delay typ. 37 ns with 3 ns channel-to-channel mismatch
– Max. delay variation ~14 ns
– Optimized for area and system BOM
– Isolation and driver in one package
– Low power dissipation due to low on-resistance
– Output stages with 5 A reverse current capability
– Robust design against switching noise
– Floating drivers are able to handle large inductive voltage over- and undershoots
– Very good common mode transient immunity CMTI >150 V/ns
– Undervoltage lockout function for switch protection
– Output- to -output channel isolation due to functional level galvanic isolation
– Input- to output channel isolation due to functional and reinforced galvanic isolation
