Pin Description
PWRGD –
The Power Good Output Pin is held inactive on initial
power application and will go active when the external MOSFET
is fully turned on. This pin may be used as an enable control
when connected directly to a PWM power module.
OV –
high threshold will immediately cause the GATE pin to be pulled
low. The GATE pin will remain low until the voltage on this pin falls
below the low threshold limit, initiating a new start-up cycle.
UV
– This UnderVoltage (UV) sense pin, when below its low
threshold limit will immediately cause the GATE pin to be pulled
low. The GATE pin will remain low until the voltage on this pin
rises above the high threshold limit, initiating a new start-up
cycle.
V
– This pin is the negative terminal of the power supply input
to the circuit.
V
–
This pin is the positive terminal of the power supply input
to the circuit.
RAMP –
This pin provides a current output so that a timing ramp
voltage is generated when a capacitor is connected.
GATE –
This is the Gate Driver Output for the external N-
Channel MOSFET.
SENSE –
The current sense resistor connected from this pin to
V
EE
Pin programs the circuit breaker trip limit.

inactive state. Thereafter a programmable auto-retry timer will
hold the device off to allow the pass element to cool before
resetting and restarting. The auto-retry can be disabled using a
single resistor if desired.
The HV301/HV311 includes a current mode servo-circuit which
can be used as a return to limit during input voltage steps such
as would be seen in a diode “ORed” situation when power
switches back to regulated supply from battery operation. The
HV301/HV311 allow independent programming of the trigger
level of this phenomenon so that it may be set at a different level
to the current limit level if desired. Under all circumstances the
maximum servo period is limited to 100ms to protect the pass
element.
