DESCRIPTION
The UCC27511 and UCC27512 single-channel high-
speed low-side gate-driver device is capable of
effectively driving MOSFET and IGBT power
switches. Using a design that inherently minimizes
shoot-through current, UCC27511 and UCC27512
are capable of sourcing and sinking high peak-current
pulses into capacitive loads offering rail-to-rail drive
capability and extremely small propagation delay
typically 13 ns.

Threshold, (independent of supply voltage)
The UCC27511 and UCC27512 provides 4-A source,
8-A sink (asymmetrical drive) peak-drive current
capability. Strong sink capability in asymmetrical drive
boosts immunity against parasitic, Miller turnon effect.
The UCC27511 device also features a unique split
output configuration where the gate-drive current is
sourced through OUTH pin and sunk through OUTL
pin. This unique pin arrangement allows the user to
apply independent turnon and turnoff resistors to the
OUTH and OUTL pins respectively and easily control
the switching slew rates.
