The UCC21551x-Q1 is an isolated dual channel gate driver family with programmable dead time and wide temperature range. This device exhibits consistent performance and robustness under extreme temperature conditions. It is designed with 4-A peak-source and 6-A 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 5-kV RMS isolation barrier, with a minimum of 125-V/ns common-mode transient immunity (CMTI).
Protection features include: resistor programmable dead time, disable feature to shut down both outputs simultaneously, integrated de-glitch filter that rejects input transients shorter than 5 ns, and negative voltage handling for up to –2-V spikes for 200 ns on input and output pins. All supplies have UVLO protection.
The UCC21551x-Q1 device accepts VDD supply voltages up to 25 V. An input VCCI range from 3 V to 5.5 V makes the driver suitable for interfacing with digital controllers. All supply voltage pins have undervoltage lock-out (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.
