... Data Sheet 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 10µ ...

... The current at current limit onset is equal to 10µ SENSE R ). The ISL6161 is limited to a 10kΩ min. value (OC Vth = 100mV) resistor whereas SENSE the ISL6161 can accommodate a 5kΩ resistor for a lower OC Vth (50mV). Connect to the load side of sense resistor to measure the voltage drop across this resistor. ...
