ISL6161CB

Hot Swap Controllers Overview

The ISL6161CB is a dual-channel hot swap power distribution controller designed for PCI Express applications. It operates with a supply voltage range of 10.5 V to 13.2 V and draws a channel operating supply current of 10 mA. The device supports two external N-channel MOSFETs for precise power management. It features programmable overcurrent protection and adjustable turn-on ramps, enabling controlled insertion and removal of modules without disrupting system operation.

Hot Swap Controllers Feature Summary

• Dual-channel architecture supporting independent control of two power rails
• Integrated charge pump facilitates the use of N-channel MOSFETs for high-side switching
• Programmable overcurrent protection allows customization for specific port power requirements
• Adjustable turn-on ramp controls soft-start timing to manage inrush currents

Hot Swap Controllers Applications

• PCI Express (PCIe) slot power distribution
• Hot swap module insertion systems
• Dual-rail power management controllers

Hot Swap Controllers Procurement Notes

Verify the exact suffix against the manufacturer's official documentation to confirm package type and temperature rating. Ensure compatibility with the target PCIe slot specifications. Confirm RoHS compliance status through the latest datasheet revision. Cross-reference pinouts with the specific package variant to prevent installation errors.

Hot Swap Controllers Selection Notes

Select this component for designs requiring dual-channel hot swap capabilities within the PCIe standard voltage envelope. Evaluate the need for external N-channel MOSFETs versus integrated solutions based on cost and board space constraints. Consider the programmability of overcurrent thresholds to match the specific load requirements of the connected peripherals.

Hot Swap Controllers Part Context

This part belongs to the Intersil hot swap controller family, which includes single-channel variants like the ISL6115 and ISL6120. While those devices target specific fixed voltages such as +12V or +2.5V, the ISL6161CB focuses on dual-channel flexibility for PCIe interfaces. The family shares common design philosophies regarding soft-start and overcurrent protection mechanisms.

Hot Swap Controllers Replacement Considerations

Check for direct substitutes within the ISL61xx series that offer similar dual-channel functionality. Verify if alternative manufacturers provide PCIe-compatible hot swap controllers with matching pinouts and electrical characteristics.
