DATASHEET
ISL6161
Dual Power Distribution Controller
The
ISL6161
is a hot swap dual supply power distribution
controller that can be used in PCI Express (PCIe) 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
10µA current source. Capacitors on each gate create a
programmable ramp (soft turn-on) to control in-rush currents,
as
Figure 1
shows. A built-in charge pump supplies the gate
drive for the 12V supply N-channel MOSFET switch.
Two external current sense resistors and FETs provide
overcurrent (OC) protection. When the current through either
resistor exceeds the user programmed value, the controller
enters Current Regulation mode. The timeout capacitor, C
TIM
,
starts charging as the controller enters the timeout period.
When C
TIM
charges to a 2V threshold, both 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 timeout 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 Voltage Threshold (Vth) is ~10.8V and the
3.3V Vth is ~2.85V nominally.
