HV301/HV311
Application Information, cont’d.
Application Circuit 11
Increasing Under Voltage Hysteresis
If the internally fixed under voltage hysteresis is insufficient for a
particular system application, then it may be increased by using
separate resistor dividers for OV and UV and providing a resistor
feedback path from the GATE pin to the UV pin (
Application
Circuit 11
).
If a system requires the use of a short connector pin on the
negative supply lead to guarantee that the power pins are fully
mated before the hotswap control circuit is enabled and uses
separate resistor dividers for UV and OV, then a 6.2V to 10V
zener diode must be connected from the OV pin to the V
pin and
only the OV divider should be connected to the short pin
(
Application Circuit 10
).
