The UCC21231 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. UCC21231
is designed with 4A peak-source and 6A peak-sink current to drive power MOSFET, and
GaN transistors.
The UCC21231 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 1.6kVRMS isolation barrier, with a minimum of
125V/ns common-mode transient immunity (CMTI).
Protection features include: resistor
programmable dead time, enable feature to shut down both outputs simultaneously,
integrated de-glitch filter that rejects input transients shorter than 5ns, and
negative voltage handling for up to –2V spikes for 200ns on input and output pins.
All supplies have UVLO protection.
The UCC21231 device accepts VDD supply voltages up to
25V. An input VCCI range from 3V to 5.5V 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
UCC21231 device enables high efficiency,
high power density, and robustness in a wide variety of power
applications.
