Automotive Reinforced, 4A/6A dual-channel isolated gate driver w/ enable, programable dead time

The UCC21551x-Q1 is an isolated dual channel

gate driver family with programmable dead time and wide temperature range. The

device is designed with 4A peak-source and 6A peak-sink current to drive power

MOSFET, SiC, and IGBT transistors.

The UCC21551x-Q1 can be configured as two

low-side drivers, two high-side drivers, or a half-bridge driver. The input side is

isolated from the two output drivers by a 5kVRMS isolation barrier, with a minimum of 125V/ns common-mode

transient immunity (CMTI). DFJ28 package offers >5.3mm CH-to-CH creepage to support high voltage

systems.

Protection features include: resistor

programmable dead time, disable feature to shut down both outputs simultaneously,

and integrated de-glitch filter that rejects input transients shorter than 5ns. All

supplies have UVLO protection.

With all these advanced features, the

UCC21551x-Q1 device enables high efficiency,

high power density, and robustness in a wide variety of power

applications.
