The UCC2742x 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 PowerPAD? 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 4A 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. Table 7-1 highlights more details about UCC2742x.
| FEATURE | BENEFIT |
|---|---|
| 1-ns (typ) delay matching between channels | Ease of paralleling outputs for higher (2 times) current capability, ease of driving parallel-power switches |
| Expanded VDD operating range of 4 to 15 V | Flexibility in system design |
| Outputs enabled when enable pins (ENx) in floating condition | Pin-to-pin compatibility with the UCC27324 device from Texas Instruments and industry standard pinout, in designs where Pin 1 and Pin 8 are in floating condition |
| CMOS/TTL compatible input and enable threshold with wide hysteresis | Enhanced noise immunity, while retaining compatibility with microcontroller logic-level inputs signals (3.3 V, 5 V) optimized for digital power |
| Ability to handle –5 VDC (max) at input pins (INA/B) | Increased robustness in noisy environments |
