HV301/HV311
If separate resistor dividers are used for OV and UV, then only
the positive (V
) end of the UV resistor divider should be
connected to the short pin (
Application Circuit 8
).
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 a single
resistor divider string (R1, R2 and R3) is used, then a 6.2V to 10V
zener diode must be connected from the UV pin to the V
