ISL6152CB

Hot Swap Controllers Overview

The ISL6152CB is a single-channel hot swap controller from the IntelliTrip series, designed for -48V and VoIP applications. It operates with a supply voltage range of 20V to 80V and draws 2.6 mA of supply current. The device features programmable overcurrent detection, current regulation, fault timeout, overvoltage protection (OVP), and undervoltage lockout (UVLO). It utilizes an external N-Channel MOSFET controlled via an internal charge pump. The component is housed in a 14-SOIC package and supports automatic retry functionality.

Hot Swap Controllers Feature Summary

• IntelliTrip technology providing precise current limiting and soft-start capabilities
• Internal charge pump enabling control of external N-Channel MOSFETs
• Programmable protection thresholds including overcurrent, OVP, and UVLO
• Automatic retry feature for transient fault recovery

Hot Swap Controllers Applications

• -48V telecommunications power distribution systems
• Voice over IP (VoIP) equipment power management
• Hot swap module insertion protection in chassis backplanes

Hot Swap Controllers Procurement Notes

Verify RoHS compliance status as the CB suffix variant may not meet current environmental standards compared to ZA variants. Confirm package dimensions against design files due to potential legacy manufacturing updates. Check for active replacement recommendations from Renesas given the discontinued status of this specific part number.

Hot Swap Controllers Selection Notes

Select this controller for -48V systems requiring robust hot swap protection without integrated switches. Ensure the external MOSFET selection matches the internal charge pump drive capability. Verify that the programmable threshold ranges align with system safety requirements for overcurrent and overvoltage events.

Hot Swap Controllers Part Context

Part of the Intersil IntelliTrip family, now managed by Renesas Electronics following the acquisition. This component addresses power distribution needs in telecom infrastructure where module insertion must be safe and controlled.
