The UCC27423/4/5 family of high-speed dual MOSFET drivers can deliver large peak currents into capacitive loads.Three standard logic options are offered dual-inverting, dual-noninverting and one-inverting and one-noninverting driver. The thermally enhanced 8-pin PowerPADTM MSOP package (DGN) drastically lowers the thermal resistance to improve long-term reliability. It is also offered in the standard SOIC-8 (D) or PDIP-8 (P) packages. Using a design that inherently minimizes shoot-through current, these drivers deliver 4-A of current where it is needed most at the Miller plateau region during the MOSFET switching transition. A unique BiPolar and MOSFET hybrid output stage in parallel also allows efficient current sourcing and sinking at low supply voltages. The UCC27423/4/5 provides enable (ENBL) functions to have better control of the operation of the driver applications. ENBA and EBBB are implemented on pins 1 and 8 which were previously left unused in the industry standard pin-out. They are internally pulled up to Vdd for active high logic and can be left open for standard operation.

Notes: 1. 125°C operating junction temperature is used for power rating calculations 2. The range of values indicates the effect of pc-board. These values are intended to give the system designer an indication of the best and worst case conditions. In general, the system designer should attempt to use larger traces on the pc-board where possible in order to spread the heat away form the device more effectively.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. All voltages are with respect to GND. Currents are positive into, negative out of the specified terminal.

NOTES: 1. Ensured by design. Not tested in production. 2. The pullup / pulldown circuits of the driver are bipolar and MOSFET transistors in parallel. The pulsed output current rating is the combined current from the bipolar and MOSFET transistors. 3. The pullup / pulldown circuits of the driver are bipolar and MOSFET transistors in parallel. The output resistance is the RDS(ON) of the MOSFET transistor when the voltage on the driver output is less than the saturation voltage of the bipolar transistor.
