3 Description
The UCC27624-Q1 is a dual-channel, high-speed,
low-side gate driver that effectively drives MOSFET,
IGBT, SiC, and GaN power switches. UCC27624-Q1
has a typical peak drive strength of 5 A, which
reduces rise and fall times of the power switches,
lowers switching losses, and increases efficiency.
The device's fast propagation delay (17-ns typical)
yields better power stage efficiency by improving the
deadtime optimization, pulse width utilization, control
loop response, and transient performance of the
system.
UCC27624-Q1 can handle –10 V at 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 independently of main control logic. In
the event of a system fault, the gate driver can quickly
shut-off by pulling enable low. Many high-frequency
switching power supplies exhibit noise at the gate
of the power device, which can get injected into the
output pin on the gate driver and can cause the driver
to malfunction. The device's transient reverse current
and reverse voltage capability allow it to tolerate noise
on the gate of the power device or pulse-transformer
and avoid driver malfunction.
The UCC27624-Q1 also features undervoltage
lockout (UVLO) for improved system robustness.
When there is not enough bias voltage to fully
enhance the power device, the gate driver output is
held low by the strong internal pull down MOSFET.
