Frequently Asked Questions
What is the peak output current of the UCC27423DG4?
The UCC27423DG4 provides a nominal peak output current of 4A through its totem-pole output stage, enabling rapid charging and discharging of MOSFET gate capacitances for fast switching transitions, reduced switching losses, and improved efficiency in power converter designs.
What is the output polarity and configuration of the UCC27423DG4?
The UCC27423DG4 features inverted output polarity with a totem-pole output stage, meaning the output goes low when the input is high. It has two output channels (low-side drivers) configured for driving power MOSFETs in non-isolated gate drive applications such as synchronous rectification and half-bridge converters.
What package does the UCC27423DG4 come in?
The UCC27423DG4 is available in an 8-pin SOIC package (JESD-30 code R-PDSO-G8), a widely used surface-mount format that provides easy PCB assembly and compatibility with standard 8-pin SOIC footprints in power supply and motor drive board designs.
What are typical applications for the UCC27423DG4?
The UCC27423DG4 is commonly used in synchronous buck converters, half-bridge power stages, full-bridge motor drives, UPS inverters, and DC-DC power modules where a dual low-side gate driver with 4A peak current and inverted output logic is needed to efficiently switch power MOSFETs or IGBTs.
