1 Features 3 Description
The UCC2752x family of devices are dual-channel,
1• Industry-Standard Pinout
high-speed, low-side gate-driver devices capable of
• Two Independent Gate-Drive Channels effectively driving MOSFET and IGBT power
• 5-A Peak Source and Sink-Drive Current switches. Using a design that inherently minimizes
• Independent-Enable Function for Each Output shoot-through current, UCC2752x can deliver highpeak current pulses of up to 5-A source and 5-A sink
• TTL and CMOS Compatible Logic Threshold into capacitive loads along with rail-to-rail drive Independent of Supply Voltage capability and extremely small propagation delay
• Hysteretic-Logic Thresholds for High Noise (typically 13 ns). In addition, the drivers feature
Immunity matched internal propagation delays between the two
channels. These delays are very well suited for • Inputs and Enable Pin-Voltage Levels Not
Restricted applications requiring dual-gate drives with critical by VDD Pin Bias Supply Voltage
timing, such as synchronous rectifiers. This also
• 4.5-V to 18-V Single-Supply Range enables connecting two channels in parallel to

compatible low-voltage logic, which is fixed and • Fast Propagation Delays (13-ns Typical)
independent of the VDD supply voltage. Wide
• Fast Rise and Fall Times (7-ns and 6-ns Typical) hysteresis between the high and low thresholds offers
• 1-ns Typical Delay Matching Between Two excellent noise immunity.
