Frequently Asked Questions
What is the peak output current of the UCC27323DGNRG4?
The UCC27323DGNRG4 delivers 4 A nominal peak output current (4.5 A maximum) per channel. This high peak current rapidly charges and discharges the gate capacitance of power MOSFETs or IGBTs, enabling fast switching transitions that reduce switching losses in high-frequency power conversion applications.
What does the inverted output polarity of the UCC27323DGNRG4 mean?
The inverted output means the gate driver output is logic-LOW when the input signal is logic-HIGH. This inverted characteristic is useful in push-pull topologies and half-bridge designs where the upper and lower gate drive signals are naturally complementary, allowing both switches to be driven from the same PWM control signal without external inverter logic.
Is the UCC27323DGNRG4 suitable for high-frequency switching applications?
Yes. Its 4.5 A peak output capability and totem-pole output structure enable rapid MOSFET gate charging even at switching frequencies of hundreds of kilohertz. The HVSSOP package with exposed thermal pad also helps manage the power dissipation in the driver at high duty cycles and switching frequencies found in telecom and industrial power converters.
How many output channels does the UCC27323DGNRG4 provide?
It integrates two independent gate driver channels in a single 8-pin HVSSOP package, with each channel capable of delivering 4.5 A peak. Using both channels, a designer can drive two separate power switches—such as the two switches in a synchronous buck converter or the two legs of a push-pull stage—from a single compact device.
