Glitch-Free Operation at Power Up and Power 3 Description

Down) The UCC27511 and UCC27512 single-channel, highspeed,

low-side gate-driver device can effectively • TTL and CMOS Compatible Input-Logic Threshold drive MOSFET and IGBT power switches. Using a

(Independent of Supply Voltage) design that inherently minimizes shoot-through

• Hysteretic-Logic Thresholds for High-Noise current, UCC27511 and UCC27512 are capable of

Immunity sourcing and sinking high peak-current pulses into
