Implementing PWRGD Control
Due to the HV100’s small footprint, it is possible to create an
open drain PWRGD signal using external components and
still maintain a size comparable with the smallest hotswap
controllers available elsewhere. To accomplish this an ex-
ternal MOSFET may be used in conjunction with the GATE
output. Simply use a high impedance divider (10MΩ) sized
so that the open drain PWRGD MOSFET threshold will only
be reached once the HV100’s GATE voltage rises well above
the current limit value required by the external MOSFET pass
device. Alternatively a Zener diode between the GATE output
and the PWRGD MOSFET GATE set at a voltage higher than
the maximum pass element V
