6.1 Overview

The UCC27524A device represents Texas Instruments’ latest generation of dual-channel, low-side, high-speed, gate-driver devices featuring a 5-A source and sink current capability, industry best-in-class switching characteristics, and a host of other features listed in Table 6-1 all of which combine to ensure efficient, robust and reliable operation in high-frequency switching power circuits.

Table 6-1 UCC27524A Features and Benefits
FEATURE BENEFIT
Best-in-class 17-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 +150 °C
(See Electrical Characteristics table)		 Flexibility in system design
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 Protection 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 the UCC27324 device from Texas Instruments, 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 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
Ability to handle –5 VDC (max) at input pins Increased robustness in noisy environments
