GaN EiceDRIVER™ product family Single-channel functional and reinforced isolated gate-drive ICs for high-voltage enhancement-mode GaN HEMTs
●Description
■CoolGaN™ and similar GaN switches require a continuous gate current of a few mA in their "on" state. Besides, due to low threshold voltage and extremely fast switching transients, a negative "off" voltage level may be needed. The widely used RC-coupled gate driver fulfils these requirements, however it suffers from a duty-cycle dependence of switching dynamics and the lack of negative gate drive in specific situations.
■Infineon's GaN EiceDRIVER™ solves these issues with very low effort. The two output stages shown below enable a zero “off" level to eliminate any duty-cycle dependence. In addition, the differential topology is able to provide negative gate drive without the need for a negative supply voltage. However, it requires a floating supply voltage not compatible with bootstrapping.
●Features
■Dedicated gate driver ICs for high-voltage GaN power switches (CoolGaN™, GIT technology based products)
▲low driving impedance (on-resistance 0.85 Ω source, 0.35 Ω sink)
▲resistor programmable gate current (typ. 10 mA) in steady “on” state
▲programmable negative gate voltage to completely avoid spurious turn-on
■Single output supply voltage (typ. 8 V, floating)
■Switching behavior independent of duty-cycle (2 "off" voltage levels)
■Differential concept to ensure negative gate drive voltage under any condition
■Fast input-to-output propagation (37 ns) with excellent stability (+7/-6 ns)
■Galvanic input-to-output isolation based on coreless transformer (CT) technology
■Common mode transient immunity (CMTI) > 200 V/ns
■3 package versions
▲1EDF5673K: 13-pin LGA (5 x 5 mm, PG-TFLGA-13-1) for functional isolation (1.5 kV)
