UCC21530QDWKRQ1

The UCC21530-Q1 is an isolated dual-channel gate driver with 4A peak source current and 6A peak sink current. The driver is designed to drive IGBTs, Si MOSFETs, and SiC MOSFETs at up to 5MHz, with excellent propagation delay and pulse width distortion performance. The input side is isolated from both output drivers by a 5.7kV_RMS reinforced isolation barrier, with a common-mode transient immunity (CMTI) of at least 100V/ns. The internal functional isolation between the two secondary-side drivers supports operating voltages up to 1850V. The driver can be configured as two low-side drivers, two high-side drivers, or a half-bridge driver with programmable dead time (DT). Pulling the EN pin low simultaneously disables both outputs, while leaving it floating or pulling it high restores normal device operation. As a failsafe mechanism, a primary-side logic fault forces both outputs low. This device accepts VDD supply voltages up to 25V. The wide input voltage VCCI range of 3V to 18V makes the driver suitable for interfacing with both digital and analog controllers. All supply voltage pins feature undervoltage lockout (UVLO) protection.
