ISL61851ACBZ

Hot Swap Controllers Overview

The ISL61851ACBZ 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 supports surface mount installation in an 8-SOIC package with a width of 3.90mm. Key electrical specifications include a maximum output current of 600mA and a supply current of 50µA. It functions reliably across a commercial temperature range of 0°C to 70°C.

Hot Swap Controllers Feature Summary

• Integrates dual-channel protection logic specifically optimized for USB port power management
• Includes built-in thermal limiting and under-voltage lockout mechanisms for enhanced system safety
• Features fault timeout and latch-off capabilities to manage overcurrent and short circuit events

Hot Swap Controllers Applications

• USB hub circuits requiring per-port power control
• Peripheral devices needing hot plug protection
• Industrial systems utilizing USB connectivity for data or power

Hot Swap Controllers Procurement Notes

Verify component authenticity through authorized channels as the part is officially discontinued. Confirm that the 8-SOIC package dimensions match your PCB footprint requirements. Ensure compliance with RoHS3 standards if applicable to your manufacturing process. Check for moisture sensitivity level 2 handling requirements during storage and assembly. Validate that the specific suffix ACBZ corresponds to the desired temperature grade and packaging format.

Hot Swap Controllers Selection Notes

Select this component when designing USB interfaces that require integrated dual-channel hot swap protection without external FETs. Consider the 8-SOIC package constraints for board space limitations. Evaluate the 50µA supply current against low-power design goals. Verify compatibility with the 2.3V to 5.5V operating voltage range of your target system. Assess the need for latch-off fault behavior versus non-latching alternatives.

Hot Swap Controllers Part Context

This device belongs to the ISL6185XXC series of hot swap controllers from Renesas. It is part of a broader portfolio of power management ICs focused on protecting sensitive electronics during insertion and removal events. The series typically targets consumer and industrial USB applications where reliable power sequencing and fault isolation are critical.
