UCC21540-Q1 Reinforced Isolation Dual-Channel Gate Driver
1 Features
3 Description
•
AEC Q100 qualified with:
– Device temperature grade 1
The UCC21540-Q1 device is an isolated dual channel
gate driver 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, IGBT, and GaN transistors.
– Device HBM ESD classification level H2
– Device CDM ESD classification level C6
Functional Safety Quality-Managed
– Documentation available to aid functional safety
system design
•
The UCC21540-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 5.7-kVRMS isolation barrier, with a minimum of
100-V/ns common-mode transient immunity (CMTI).
•
•
Junction temperature range –40°C to 150°C
Up to 18-V VDD output drive supply
– 5-V and 8-V VDD UVLO Options
CMTI greater than 100 V/ns
•
•
Switching parameters:
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 5ns, and negative
voltage handling for up to –2V spikes for 200ns on
input and output pins. All supplies have UVLO
protection.
– 40-ns maximum propagation delay
– 5-ns maximum delay matching
– 5.5-ns maximum pulse-width distortion
– 35-µs maximum VDD power-up delay
Safety-related certifications:
– 8000-VPK reinforced isolation per DIN V VDE V
0884-11:2017-01
– 5700-VRMS isolation for 1 minute per UL 1577
– CQC certification per GB4943.1-2011
