| FEATURE | BENEFIT |
|---|---|
| High Source and Sink Current Capability 4 A and 8 A (Asymmetrical) – UCC2751/6/7/8/9 4 A and 4 A (Symmetrical) – UCC27511 and UCC27512 |
High current capability offers flexibility in employing UCC2751x family of devices to drive a variety of power switching devices at varying speeds |
| Best-in-class 13-ns (typ) Propagation delay | Extremely low pulse-transmission distortion |
| Expanded VDD Operating range of 4.5 V to 18 V | Flexibility in system design Low VDD operation ensures compatibility with emerging wide band-gap power devices such as GaN |
| Expanded Operating Temperature range of –40°C to 140°C (See Electrical Characteristics table) |
|
| VDD UVLO Protection | Outputs are held low in UVLO condition, which ensures predictable glitch-free operation at power up and power down |
| Outputs held low when input pins (INx) in floating condition | Safety feature, especially useful in passing abnormal condition tests during safety certification |
| Ability of input pins (and enable pin in UCC27518/9) to handle voltage levels not restricted by VDD pin bias voltage | System simplification, especially related to auxiliary bias supply architecture |
| Split output structure in UCC27511 (OUTH, OUTL) | Allows independent optimization of turnon and turnoff speeds |
| Strong sink current (8 A) and low pulldown impedance (0.375 Ω) in UCC27511 and UCC27512 | High immunity to C x dV/dt Miller turnon events |
| CMOS/TTL compatible input-threshold logic with wide hysteresis in UCC27511, UCC27512, UCC27516 and UCC27517 | Enhanced noise immunity, while retaining compatibility with microcontroller logic-level input signals (3.3 V, 5 V) optimized for digital power |
| CMOS input threshold logic in UCC27518/9 (VIN_H – 70% VDD, VIN_L – 30% VDD) | Well suited for slow input-voltage signals, with flexibility to program delay circuits (RCD) |
