MAX5901ACEUT+T

Hot Swap Controllers Overview

The MAX5901ACEUT+T is a hot-swap voltage controller designed for -48V telecommunications applications. It operates within a supply voltage range of -100V to -9V and features adjustable current limiting. The device includes under-voltage lockout (UVLO) and fault timeout protection with latch-off capability. It consumes 500 µA of operating supply current and functions reliably between -40°C and +85°C. Packaged in a surface-mount SOT-23-6 format, it provides comprehensive power-supply sequencing and transient immunity.

Hot Swap Controllers Feature Summary

• Provides integrated protection against input voltage transients during hot-swap operations
• Features programmable under-voltage lockout and fault timeout mechanisms
• Includes thermal limiting and latch-off fault protection for circuit safety

Hot Swap Controllers Applications

• -48V telecom line cards
