SiC778A
Vishay Siliconix
Under Voltage Lockout (UVLO)
During the start up cycle, the UVLO disables the gate drive
holding high-side and low-side MOSFET gate low until the
incorporates logic to clamp the gate drive signals to zero
when the UVLO falling edge triggers the shutdown of
the device. As an added precaution, a 20.2 k ? resistor
input voltage rail has reached a point at which the
is connected between GH
and PHASE to provide
logic circuitry can be safely activated. The SiC778A also
a discharge path for the HS MOSFET.
