Key Features
- 3 A peak source/sink drive current switches MOSFETs and GaN FETs up to 120 V bus with minimal deadtime
- Integrated interlock and enable prevent shoot-through, improving half-bridge reliability without external logic
- 5 V UVLO and Schmitt-trigger inputs reject noise on high-dV/dt switching nodes in compact 8-pin WSON
Applications
The UCC27282DRMR is designed for half-bridge power stages in DC-DC converters, LLC resonant converters, and motor drive inverters operating at bus voltages up to 120 V. Its 3 A gate drive capability rapidly charges MOSFET or GaN gate capacitances for switching frequencies up to several hundred kilohertz, minimizing switching losses. The integrated interlock feature and 5 V UVLO simplify the control circuit and improve system robustness in industrial power supplies and motor controllers.

Frequently Asked Questions
What peak gate drive current can UCC27282DRMR deliver, and up to what bus voltage is it rated?
The UCC27282DRMR delivers 3 A peak source and 3 A peak sink gate drive current, rated for half-bridge topologies with bus voltages up to 120 V. This combination allows fast switching of high-capacitance MOSFETs or GaN FETs at frequencies above 200 kHz while keeping switching losses low in DC-DC converter and motor drive designs.
How does the built-in interlock function of UCC27282DRMR protect a half-bridge power stage?
The integrated interlock circuit in UCC27282DRMR prevents both the high-side and low-side outputs from being active simultaneously, eliminating shoot-through current through the switching FETs regardless of the PWM input timing. This hardware interlock adds a minimum deadtime of approximately 25 ns and removes the need for an external deadtime logic circuit, saving board space and reducing component count in 120 V power stages.
For a 48 V LLC resonant converter running at 300 kHz, how does UCC27282DRMR compare to a dual discrete gate driver approach?
At 300 kHz switching frequency with a 48 V bus, UCC27282DRMR replaces two individual gate driver ICs plus external interlock and UVLO circuitry, typically saving 4 to 6 passive components and up to 30% PCB area. Its 3 A drive strength charges a 10 nF MOSFET gate in under 10 ns, and the 5 V UVLO ensures the driver stays off safely during power ramp-up, which is critical in resonant topologies.
