ISL6140IB

Hot Swap Controllers Overview

The ISL6140IB is a single-channel hot swap controller designed for -48V and VoIP applications. It operates with a supply voltage range of 10V to 80V and draws 900 µA of supply current. The device features programmable circuit breaker, fault timeout, overvoltage protection (OVP), and undervoltage lockout (UVLO). It utilizes an 8-SOIC package and supports surface mount installation. The component includes internal latch-off fault logic and functions without an internal switch.

Hot Swap Controllers Procurement Notes

Verify the specific suffix against official documentation, as availability varies by variant. Confirm RoHS3 compliance status and check for product change notices regarding manufacturing site updates or label changes. Ensure the selected part number matches the required package type and operating temperature range for the target application environment.

Hot Swap Controllers Selection Notes

Select this controller for -48V systems requiring precise power sequencing and protection. Verify that the external N-Channel MOSFET selection aligns with the controller's drive capabilities and thermal requirements. Ensure the UVLO threshold settings match the system's minimum operating voltage constraints to prevent premature shutdown during startup transients.
