3 Description
The UCC27614-Q1 is a single channel, high-speed,
low-side gate driver capable of effectively driving
MOSFET, IGBT, SiC, and GaN power switches. The
UCC27614-Q1 has a typical peak drive strength
of 10A, which reduces the rise and fall times of
the power switches, lowering switching losses and
increasing efficiency. The small propagation delay
of the UCC27614-Q1 yields better power stage
efficiency by improving dead-time optimization, pulse
width utilization, control loop response, and transient
performance of the system.
The UCC27614-Q1 can handle –10V on its inputs,
which improves robustness in systems with moderate
ground bouncing. The inputs are independent of
supply voltage and can be connected to most
controller outputs for maximum control flexibility. An
independent enable signal allows the power stage to
be controlled independent of the main control logic.
The gate driver can quickly shut off the power stage
if there is a fault in the system (which requires the
power train to be turned off). The enable function also
improves system robustness. Many high-frequency
switching power supplies exhibit high frequency noise
at the gate of the power device, which can get
injected into the output pin of the gate driver and can
cause the driver to malfunction. The UCC27614-Q1
performs well in such conditions due to its transient
reverse current and reverse voltage capability.
The strong internal pulldown MOSFET holds the
output low if the VDD voltage is below the specified
UVLO threshold. This active pulldown feature further
improves system robustness. The 10A drive current
of the UCC27614-Q1 in the 2mm × 2mm package
improves system power density. This small package
also enables optimum gate driver placement and
improved layout.
