7.1 Overview

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.

Table 7-1 UCC2752x Family of Features and Benefits
FEATUREBENEFIT
Best-in-class 13-ns (typ) propagation delayExtremely low-pulse transmission distortion
1-ns (typ) delay matching between channelsEase of paralleling outputs for higher (2 times) current capability, ease of driving parallel-power switches
Expanded VDD Operating range of 4.5 to 18 VFlexibility in system design
Expanded operating temperature range of –40°C to 140°C
(See Section 6.5)
VDD UVLO ProtectionOutputs 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 conditionSafety feature, especially useful in passing abnormal condition tests during safety certification
Outputs enable when enable pins (ENx) in floating conditionPin-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 hysteresisEnhanced 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 voltageSystem simplification, especially related to auxiliary bias supply architecture
