GaN EiceDRIVER™ product family
Single-channel functional and reinforced isolated gate-drive ICs for
high-voltage enhancement-mode GaN HEMTs
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)
– 1EDF5673F: 16-pin P-DSO (150 mil, PG-DSO-16-11) for functional isolation (1.5 kV)
– 1EDS5663H: 16-pin P-DSO (300 mil, PG-DSO-16-30) for reinforced isolation
• Fully qualified according to JEDEC for Industrial Applications
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.
