ISL6161CB Description

The ISL6161CB is a hot swap controller designed for high reliability and efficient power management in demanding applications such as PCI Express® systems. Manufactured by Intersil, this device offers robust performance within an operating temperature range of 0°C to 70°C, making it suitable for a variety of industrial and commercial environments. The ISL6161CB features a surface mount package, which allows for compact and reliable integration into modern electronic systems.

This hot swap controller is designed to manage power supply circuits with adjustable current limits and fault timeouts, providing precise control over power delivery. It operates with a supply voltage range of 10.5V to 13.2V and draws a supply current of 8 mA, ensuring efficient power usage and minimal energy loss. The ISL6161CB includes latched fault protection, which enhances system reliability by preventing transient faults from causing unintended power interruptions.

ISL6161CB Features

The ISL6161CB stands out with its unique features and programmable options that provide enhanced control and flexibility. Key features include:

• Programmable Current Limit: This feature allows users to set the maximum current that the controller will allow, preventing overcurrent conditions that could damage the system.
• Programmable Fault Timeout: Users can configure the duration for which the controller will tolerate a fault condition before taking corrective action, providing a balance between system protection and operational continuity.
• Latched Fault Protection: Once a fault is detected, the controller latches the fault condition, ensuring that the system remains in a safe state until the issue is resolved.
• Two Channels: The ISL6161CB supports dual channels, enabling simultaneous control of two power supply circuits, which is particularly useful in redundant power systems.

ISL6161CB Applications

The ISL6161CB is ideally suited for applications requiring reliable power management and fault protection, such as:

• PCI Express® Systems: The ISL6161CB is specifically designed to meet the stringent power management requirements of PCI Express® systems, ensuring stable power delivery and protection against transient faults.
• Redundant Power Systems: Its dual-channel capability makes it suitable for applications where redundant power supplies are used to enhance system reliability.
• Industrial Control Systems: The wide operating temperature range and surface mount package make it ideal for industrial environments where compact and reliable power management is crucial.

Conclusion of ISL6161CB

The ISL6161CB, despite being marked as obsolete, remains a robust solution for power supply circuits requiring adjustable current limits and fault protection. Its programmable features, dual-channel support, and latched fault protection make it a versatile and reliable choice for applications such as PCI Express® systems and redundant power systems.
