ISL61851BCBZ-T

Hot Swap Controllers Overview

The ISL61851BCBZ-T is a dual-channel hot swap 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 switch configuration. The device provides comprehensive overcurrent protection with fault timeout and latch-off capabilities. It is housed in an 8-SOIC package (0.154 inch width) and supports surface mount installation. The component functions across an operating temperature range of 0°C to +70°C, drawing a maximum output current of 600mA and a supply current of 50µA.

Hot Swap Controllers Feature Summary

• Dual-channel architecture providing independent overcurrent fault protection for multiple USB ports
• Integrated thermal limiting and undervoltage lockout (UVLO) for enhanced system reliability
• Internal switch design eliminates the need for external pass transistors
• Fault timeout and latch-off mechanisms ensure robust circuit protection

Hot Swap Controllers Applications

• USB port power management systems
• Hot swap controller implementations
• Circuit protection for multi-port USB hubs

Hot Swap Controllers Procurement Notes

Verify the specific suffix BCBZ-T against official Renesas documentation to confirm tape-and-reel packaging and channel configuration. Confirm RoHS3 compliance status as per the latest datasheet revision. Check for End-of-Life (EOL) notices or Product Change Notifications (PCN) regarding availability and lead times before finalizing procurement plans.

Hot Swap Controllers Selection Notes
