DESCRIPTION (CONTINUED)

Using a design that inherently minimizes shoot-through current, the outputs of these can provide high gate drive

current where it is most needed at the Miller plateau region during the MOSFET switching transition. A unique

hybrid output stage paralleling bipolar and MOSFET transistors (TrueDrive) allows efficient current delivery at low

supply voltages.With this drive architecture, UCC37321/2/3 can be used in industry standard 6-A, 9-A and many

12-A driver applications. Latch up and ESD protection circuitries are also included. Finally, the UCC37321/2

provides an enable (ENBL) function to have better control of the operation of the driver applications. ENBL is

implemented on pin 3 which was previously left unused in the industry standard pin-out. It is internally pulled up

to Vdd for active high logic and can be left open for standard operation.

In addition to SOIC-8 (D) and PDIP-8 (P) package offerings, the UCC37321/2 also comes in the thermally

enhanced but tiny 8-pin MSOP PowerPAD™ (DGN) package. The PowerPAD™ package drastically lowers the

thermal resistance to extend the temperature operation range and improve the long-term reliability.

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.
