Isolated dual-channel gate driver with single input in LGA for automotive 48-V systems with 5-V UVLO

 

Description

The UCC20225-Q1 family are single-input, dual-output isolated gate drivers with 4-A source and 6-A sink peak current in 5-mm x 5-mm LGA-13. It is designed to drive power transistors up to 5-MHz with best-in-class propagation delay and pulse-width distortion.

The input side is isolated from the two output drivers by a 2.5-kVRMS isolation barrier, with minimum 100-V/ns common-mode transient immunity (CMTI). Internal functional isolation between the two output-side drivers allows working voltage up to 700-VDC.

The UCC20225-Q1 family allow programmable dead time through a resistor on DT pin. A DIS pin shuts down both outputs simultaneously when set high, and allows normal operation when left grounded.

The device accepts VDD supply voltages up to 25-V. A wide VCCI range from 3-V to 18-V 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 UCC20225-Q1 family enables high power density, high efficiency, and robustness in a variety of automotive applications.
