UCC2751x Product Family
The UCC2751x family of gate-driver products (Table 6) represent Texas Instruments’ latest generation of single-
channel low-side high-speed gate-driver devices featuring high-source/sink current capability, industry best-in-
class switching characteristics and a host of other features (Table 7) all of which combine to ensure efficient,
robust and reliable operation in high-frequency switching power circuits.

gap power devices such as GaN
(See ELECTRICAL CHARACTERISTICS table)
Outputs are held low in UVLO condition, which ensures predictable
VDD UVLO Protection
glitch-free operation at power up and power down
Safety feature, especially useful in passing abnormal condition tests
Outputs held low when input pins (INx) in floating condition
during safety certification
Ability of input pins (and enable pin in UCC27518/9) to handle System simplification, especially related to auxiliary bias supply
voltage levels not restricted by VDD pin bias voltage architecture
Split output structure in UCC27511 and UCC27512 (OUTH, OUTL) Allows independent optimization of turnon and turnoff speeds
Strong sink current (8 A) and low pulldown impedance (0.375 Ω) in
High immunity to C x dV/dt Miller turnon events
UCC27511 and UCC27512
Enhanced noise immunity, while retaining compatibility with
CMOS/TTL compatible input-threshold logic with wide hysteresis in
microcontroller logic-level input signals (3.3 V, 5 V) optimized for
UCC27511, UCC27512, UCC27516 and UCC27517
digital power
CMOS input threshold logic in UCC27518/9 (VIN_H – 70% VDD, Well suited for slow input-voltage signals, with flexibility to program
VIN_L – 30% VDD) delay circuits (RCD)
