PRODUCTION DATA
The UCC2752x family of products represent TI’s latest generation of dual-channel, low-side, high-speed gate-driver devices featuring 5-A source and sink current capability, industry best-in-class switching characteristics and a host of other features listed in Table 7-1 all of which combine to ensure efficient, robust and reliable operation in high-frequency switching power circuits.
| FEATURE | BENEFIT |
|---|---|
| Best-in-class 13-ns (typ) propagation delay | Extremely low-pulse transmission distortion |
| 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 4.5 to 18 V | Flexibility in system design |
| Expanded operating temperature range of –40°C to 140°C (See Section 6.5) | |
| 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 |
| Outputs enable when enable pins (ENx) in floating condition | Pin-to-pin compatibility with UCC2732X family of products from TI, in designs where pin 1 and 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 input signals (3.3 V, 5 V) optimized for digital power |
| Ability of input and enable pins to handle voltage levels not restricted by VDD pin bias voltage | System simplification, especially related to auxiliary bias supply architecture |
