LTC4253BIGN#PBF

Hot Swap Controllers Overview

The LTC4253BIGN#PBF is a hot swap controller designed for -48V systems, manufactured by Analog Devices Inc. It operates within an industrial temperature range of -40°C to +85°C and is housed in a 16-SSOP package with exposed pad. The device features programmable circuit breaker thresholds, current limit settings, fault timeout durations, overvoltage protection (OVP), and undervoltage lockout (UVLO). It requires no internal switch and draws a supply current of 1.1 mA at -48V.

Hot Swap Controllers Feature Summary

• Programmable circuit breaker and current limit controls
• Integrated overvoltage and undervoltage protection
• Configurable fault timeout logic

Hot Swap Controllers Applications

• -48V telecommunications infrastructure
• Industrial control systems
• Portable instrumentation

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'IGN' against official Analog Devices documentation to confirm the exact temperature grade and package variant. Confirm RoHS compliance status directly from the manufacturer's datasheet or product change notifications prior to procurement.

Hot Swap Controllers Selection Notes

Select this component when external high-side switching is required for -48V rails. Ensure the external MOSFET selected can handle the programmed current limits and thermal dissipation requirements defined by the controller's programmable parameters.

Hot Swap Controllers Part Context

This part belongs to the LTC4253 family of hot swap controllers. It provides precise power management for sensitive loads during insertion and removal events, protecting both the load and the system bus from electrical faults.
