The LED output driver is programmed to be either open-drain with a 25 mA current sink capability at 5 V or totem pole with a 25 mA sink, 10 mA source capability at 5 V. The PCA9685 operates with a supply voltage range of 2.3 V to 5.5 V and the inputs and outputs are 5.5 V tolerant. LEDs can be directly connected to the LED output (up to.
The single-channel isolated EiceDRIVER™ GaN gate driver IC family for high-voltage gallium nitride switches was developed to drive Infineon’s CoolGaN™ 600V e-mode HEMTs, allowing for higher system efficiency and power density, associated with improved robustness and reduced costs.
Key advantages when designing with Infineon’s tailor-made EiceDRIVER™ GaN gate driver ICs are the fast turn-on and turn-off switch slew rates in source and sink driving currents. Thanks to the extended common-mode transient immunity (CMTI) robustness, these gate drivers enable extremely fast switching.
The high-side EiceDRIVER™ GaN gate drivers ensure robust and highly efficient operation of the high-voltage gallium-nitride switch, and at the same time concurrently minimizing R&D efforts and shortening time-to-market.
Infineon’s isolated EiceDRIVER™ GaN gate driver ICs provide negative VGS voltage, which leads to safe off-states during switching transients. Additionally, it protects the GaN switch against spurious turn-on, even for the first pulse or after a burst mode operation.
Thanks to the integrated galvanic isolation, Infineon’s EiceDRIVER™ GaN gate driver ICs are best suited to drive high-voltage GaN HEMTs in hard-switching half-bridge applications, such as the totem-pole PFC topology. If the PWM signals have to cross the safe isolation barrier, such as in the resonant LLC with secondary-side control, the 1EDS5663H with reinforced isolation is the right choice.
Infineon’s gallium nitride CoolGaN™ 600V e-mode HEMTs are best driven by Infineon’s EiceDRIVER™ GaN 1EDF5673K, 1EDF5673F and 1EDS5663H gate driver ICs.
