Automotive Basic, 4A/6A dual-channel isolated gate driver w/ disable, programmable deadtime

The UCC21320-Q1

is an isolated dual-channel gate driver with

4A source and 6A sink peak current. It is designed to drive power MOSFETs, IGBTs,

and SiC MOSFETs up to 5MHz.

The input side is isolated from the

two output drivers by a 3.75kVRMS basic isolation barrier, with a minimum

of 125V/ns common-mode transient immunity (CMTI). Internal functional isolation

between the two secondary-side drivers allows a working voltage of up to

1500VDC.

Every driver can be

configured as two low-side drivers, two high-side drivers, or a half-bridge driver

with programmable dead time (DT). A disable pin shuts down both outputs

simultaneously, and

allows normal operation when left open or grounded. As a fail-safe measure,

primary-side logic failures force both outputs low.

Each device accepts VDD

supply voltages up to 25V. A wide input VCCI range from 3V to 18V makes the driver

suitable for interfacing with both analog and digital controllers. All supply voltage pins have under voltage

lock-out (UVLO) protection.

With all these advanced features, the

UCC21320-Q1

enables high efficiency, high power density, and robustness.
