ISL61851BIBZ-T

Hot Swap Controllers Overview

The ISL61851BIBZ-T is a dual-channel hot swap voltage controller designed for USB applications. It integrates two P-channel MOSFET power switches within an 8-SOIC package. The device operates with a supply voltage range of 2.3V to 5.5V and features an internal current monitoring system. Key electrical specifications include a maximum output current of 1.5A per channel and a supply current of 50 µA. It supports automatic retry, fault timeout, thermal limiting, and UVLO functions.

Hot Swap Controllers Feature Summary

• Integrates dual P-channel MOSFET power switches for efficient power control
• Provides accurate internal current monitoring for each channel
• Supports automatic retry and fault timeout protection mechanisms

Hot Swap Controllers Applications

• USB port power supply control
• Dual USB port hot swap systems

Hot Swap Controllers Procurement Notes

Verify component authenticity through authorized Renesas distributors. Confirm the specific suffix matches the required tape-and-reel packaging format. Check for recent Product Change Notices regarding label updates or manufacturing site changes. Ensure compliance with RoHS3 standards and REACH regulations before integration into final designs.

Hot Swap Controllers Selection Notes

Select this component for designs requiring dual-channel USB hot swap capabilities with integrated switching. Compare against the ISL61851JCBZ for SOIC package variants or the ISL61852 series for DFN options. Evaluate the 1.5A output capability against load requirements. Consider the 50 µA supply current for low-power standby applications.
