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.

Evaluation Platform
*Intersil Pb-free 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.
