Key Features
- 4A peak source/sink totem-pole output per channel delivers rapid gate charge to MOSFETs for fast switching transitions at 100 kHz to 1 MHz
- Dual independent inverting outputs allow driving 2 low-side switches simultaneously, simplifying half-bridge and synchronous rectifier gate drive circuits
- Standard logic-level input interface accepts 3.3V or 5V PWM signals directly from digital controllers without level-shifting circuitry
Applications
UCC27323PE4 is used in synchronous buck converters, half-bridge DC-DC converters, and motor drive circuits where fast 4A gate drive is needed for low-side N-channel MOSFETs. Its dual-channel architecture allows a single IC to drive both synchronous switches in a buck stage, reducing component count and PCB area in telecom power supplies and industrial motor controllers. The 8-pin PDIP package simplifies prototyping and through-hole production builds for power electronics development boards.

Frequently Asked Questions
What peak gate drive current does UCC27323PE4 deliver, and how does that reduce MOSFET switching losses at 500 kHz?
UCC27323PE4 delivers 4A peak output current into the MOSFET gate, charging typical gate capacitances of 10 nF to 20 nF in under 50 ns. This fast gate slew reduces switching transition overlap time, cutting switching losses by roughly 30% at 500 kHz compared to a weaker 1A driver in the same synchronous buck topology.
How does the inverting output polarity of UCC27323PE4 affect PWM signal routing in a synchronous buck converter?
UCC27323PE4 has inverting outputs, so a high PWM input turns the MOSFET off and a low input turns it on. In a synchronous buck, the controller must generate complementary drive signals (or invert one channel externally) when using both UCC27323PE4 outputs for the high-side and synchronous low-side drivers, or use it solely for 2 independent low-side switches with inverted PWM polarity.
Can UCC27323PE4 drive two independent MOSFETs in a full-bridge motor controller simultaneously, and what switching frequency is supported?
UCC27323PE4 provides 2 independent output channels each rated at 4A peak, so it can drive 2 separate low-side N-channel MOSFETs in a full-bridge configuration simultaneously. The device supports switching frequencies up to at least 1 MHz with standard MOSFET gate capacitances below 15 nF, making it suitable for high-frequency DC motor drives operating at 12V to 24V bus voltages.
How does UCC27323PE4 in an 8-pin DIP compare to a more integrated gate driver module for a 5A DC-DC converter prototype?
UCC27323PE4 in an 8-pin DIP provides 4A drive per channel with minimal external components (one bypass capacitor per supply rail) at a low unit cost, making it the faster choice for breadboard or perfboard prototyping. An integrated module may add protection features, but for a 5A converter running at 12V with standard N-channel MOSFETs, the UCC27323PE4's 4A peak drive and 8-pin footprint deliver adequate performance with shorter design cycle time.
