HV301/HV311
Application Circuit 1
PWRGD Output
It is critical to have a detailed understanding of the ENABLE input
circuitry of the load (DC/DC PWM Converter) in order to make
the correct choice between the HV301 or HV311.
Many DC/DC PWM Converters reference their ENABLE inputs
to the negative input terminal. If the ENABLE input is active LOW
then the HV311 can be directly connected as shown below
(
Application Circuit 1
) since the open drain PWRGD output is
in a High-Z state until the external MOSFET is fully turned on and
the potential on the negative input of the converter is essentially
the same as the V
EE
pin of the HV311.
