Key Features
- Dual-channel 4A peak totem-pole MOSFET driver enables fast gate charge delivery for reduced switching losses in power conversion
- Non-inverting (buffer-based) and inverting drive options allow direct control from standard PWM controller outputs without additional logic
- Compact 8-pin VSSOP package reduces PCB footprint while delivering high-current gate drive for two independent switches
- RoHS-compliant Pb-free construction (JESD-609 e4) ensures suitability for modern environmentally regulated power supply designs
Applications
The UCC27424DGNG4 is used in synchronous buck converters, half-bridge, and full-bridge power topologies to drive the gate terminals of power MOSFETs and IGBTs at high switching frequencies. Its 4A peak drive current significantly reduces MOSFET switching transition times, lowering switching losses in DC-DC converters, motor drivers, and uninterruptible power supplies. The dual-channel configuration allows a single IC to drive both the high-frequency switch and its complement in non-isolated low-side designs.

Frequently Asked Questions
What is the peak output current of the UCC27424DGNG4?
The UCC27424DGNG4 provides 4A peak output current per channel from its totem-pole output stage. This high drive capability enables rapid charging and discharging of MOSFET gate capacitances, reducing switching transition times and minimizing conduction and switching losses at high frequencies.
How many channels does the UCC27424DGNG4 have and are they independent?
The UCC27424DGNG4 contains two independent gate driver channels, each with its own input and output. The two channels share the same supply and ground but operate independently, making this device suitable for driving two separate power MOSFETs or IGBTs in a converter stage.
What package does the UCC27424DGNG4 use?
The UCC27424DGNG4 is housed in an 8-pin VSSOP (Very Thin Small Outline Package), JESD-30 code S-PDSO-G8. This compact surface-mount package is well suited for high-density power supply designs where board space is limited.
Is the UCC27424DGNG4 suitable for high-side MOSFET driving?
No, the UCC27424DGNG4 is specified as a low-side gate driver (High Side Driver: NO). It is designed to drive the gate of ground-referenced (low-side) MOSFETs directly. For high-side drive applications, a bootstrap gate driver or isolated gate driver solution would be required.
What are typical applications for the UCC27424DGNG4?
This dual 4A gate driver is used in synchronous buck converters, phase-leg circuits, motor drive half-bridges, and resonant converter switch networks. Its high drive current and fast propagation reduce dead-time losses in synchronous rectification and enable efficient switching at frequencies above 500kHz in modern power management ICs.
