ISL6161
Dual Power Distribution Controller
The ISL6161 is a HOT SWAP dual supply power distribution
controller that can be used in PCI-Express applications.
Two external N-Channel MOSFETs are driven to distribute
and control power while providing load fault isolation. At turn-
on, the gate of each external N-Channel MOSFET is
charged with a 10
μ
A current source. Capacitors on each
gate (see the Typical Application Diagram), create a
programmable ramp (soft turn-on) to control inrush currents.
A built in charge pump supplies the gate drive for the 12V
supply N-Channel MOSFET switch.
Over current protection is facilitated by two external current
sense resistors and FETs. When the current through either
resistor exceeds the user programmed value the controller
enters the current regulation mode. The time-out capacitor,
C
TIM
, starts charging as the controller enters the time out
period. Once C
TIM
charges to a 2V threshold, both the
N-Channel MOSFETs are latched off. In the event of a hard
and fast fault of at least three times the programmed current
limit level, the N-Channel MOSFET gates are pulled low
immediately before entering the time out period. The
controller is reset by a rising edge on the ENABLE pin.
The ISL6161 constantly monitors both output voltages and
reports either one being low on the PGOOD output as a low.
The 12V PGOOD Vth is ~10.8V and the 3.3V Vth is ~2.8V
nominally.

NOTE: Intersil Pb-free products employ special Pb-free material sets; molding
compounds/die attach materials and 100% matte tin plate termination finish, which
is 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-020B.
