3kVrms, 4A/6A dual-channel isolated gate driver w/ disable pin, 8V UVLO

The UCC21220 and UCC21220A

devices are basic

and functional isolated dual-channel gate drivers with 4A peak-source and 6A

peak-sink current. They are designed to drive power MOSFETs and GaNFETs in PFC,

Isolated DC/DC, and synchronous rectification applications, with fast switching

performance and robust ground bounce protection through greater than

125V/ns

common-mode transient immunity (CMTI).

These devices can be configured as two

low-side drivers, two high-side drivers, or half-bridge drivers. Two outputs can be

paralleled to form a single driver which doubles the drive strength for heavy load

conditions due to the best-in-class delay matching performance.

Protection features include the

following: DIS pin shuts down both outputs simultaneously when it is set

high,

all supplies have undervoltage lockout (UVLO), and active pulldown protection clamps

the output below

2V

when unpowered or floated.

With these features, these devices

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

power applications.
