ISL61851BCBZ

Hot Swap Controllers Overview

The ISL61851BCBZ is a dual-channel hot swap voltage controller designed for USB applications, manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 2.3V to 5.5V and features an internal current limit of 600mA per channel. The device supports surface-mount installation in an 8-SOIC package with a width of 3.90mm. It functions reliably across an operating temperature range of 0°C to +70°C while consuming a maximum supply current of 50 µA.

Hot Swap Controllers Feature Summary

• Integrates dual-channel hot swap control with built-in internal switches for compact circuit design
• Provides comprehensive protection mechanisms including fault timeout, thermal limiting, and under-voltage lockout
• Supports auto-retry functionality to manage transient faults without requiring manual intervention

Hot Swap Controllers Applications

• USB port power management and protection
• Hot swap interface circuits for peripheral devices
• Overcurrent protection in low-voltage power distribution systems

Hot Swap Controllers Procurement Notes

Verify component authenticity through authorized Renesas distributors or certified partners. Confirm the specific suffix matches the required package and temperature grade. Check for end-of-life notifications as availability may be restricted. Ensure storage conditions comply with moisture sensitivity levels specified in the datasheet to prevent damage during assembly.

Hot Swap Controllers Selection Notes

Select this component when dual-channel USB hot swap capability is required with integrated switching elements. Consider the 8-SOIC package constraints for PCB layout space. Evaluate the 600mA internal switch rating against peak load requirements. Verify that the 2.3V minimum operating voltage aligns with the system's power rail specifications.
