UCC27523D

The UCC27523D is a dual high-speed low-side Gate-driver Device capable of effectively driving MOSFET and IGBT power switches. Using a design that inherently minimizes shoot-through current, UCC2752x can deliver high-peak current pulses of up to 5A source and 5A sink into capacitive loads along with rail-to-rail drive capability and extremely small propagation delay (typically 13ns). In addition, the driver feature matched internal propagation delay between the two channels. This delay is very well suited for applications requiring dual-gate drives with critical timing, such as synchronous rectifiers. This also enables connecting two channels in parallel to effectively increase current-drive capability or driving two switches in parallel with one input signal. The input pin thresholds are based on TTL and CMOS compatible low-voltage logic, which is fixed and independent of the VDD supply voltage. Wide hysteresis between the high and low thresholds offers excellent noise immunity.

• Industry-standard pin-out
• Two independent gate-drive channels
• Independent-enable function for each output
• TTL and CMOS compatible logic threshold independent of supply voltage
• Hysteretic-logic thresholds for high noise immunity
• Inputs and enable pin-voltage levels not restricted by VDD pin bias supply voltage
• Outputs held low during VDD-UVLO (ensures glitch-free operation at power up and power-down)
• Two outputs are in parallel for higher drive current
• Outputs held low when inputs floating
• 1ns Typical delay matching between two channels
• Green product and no Sb/Br
