The ISL6160 is designed to address the unique power requirements of the InfiniBand (IB) industry initiative providing independent power control of both the VB(bulk) (+12V) and the VA(auxiliary) (+5V) power rails for a single port. This device can be implemented in both IB Class I (non isolated) and Class II (isolated) Power Topology applications.

Features
• VB Programmable Overcurrent Protection Regulation Level for 25W and 50W Ports
• Internal Charge Pump Allows the Use of an N-Channel MOSFET for VB Control
• VB Adjustable Turn-On Ramp
• Soft Start Overcurrent Protection During Turn-On
• Two Levels of VB Overcurrent Detection and Protection
• VA and VB Undervoltage Lock-Outs
• 0.125Ω Integrated Power N-Channel MOSFET VA Switch
• Accurate VA Current Sensing and Limiting (1A)
• Timed Current Regulation Period (VB Optional)
• VA Controlled Turn-On Ramp Time
• 1µs Response Time to VB Secondary Rail Dead Short

Applications
• InfiniBand VB and VA Voltage Control
• -48V and 5V Telecom
