The ISL6161CBZA 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. 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, CTIM, starts charging as the controller enters the timeout period. When CTIM 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 span ENABLE/span pin.
The ISL6161CBZA 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.
