ISL6173
Dual Low Voltage Hot Swap Controller
This IC targets dual voltage hot swap applications across the
+2.5V to +3.3V (nominal) bias supply voltage range with a
second lower voltage rail down to less than 1V. It features a
charge pump for driving external N-Channel MOSFETs,
regulated current protection and duration, output undervoltage
monitoring and reporting, optional latch-off or retry response,
and adjustable soft-start.
The current regulation level (CR) for each rail is set by two
external resistors and each CR duration is set by an external
capacitor on the TIM pin. After the CR duration has expired
the IC then quickly pulls down the associated GATE(s)
output turning off its external FET(s). The ISL6173 offers a
latched output or indefinite auto retry mode of operation.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
compatible with both SnPb and Pb-free soldering operations. Intersil
Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of
IPC/JEDEC J STD-020.
