MAX5901LBEUT

Hot Swap Controllers Overview

The MAX5901LBEUT is a hot-swap voltage controller designed for single-channel applications. It supports input supply voltages ranging from 9 V to 48 V, making it suitable for -48V telecom systems and other industrial power buses. The device features an adjustable current limit with foldback protection to manage inrush currents during board insertion. Integrated power-fail detection monitors the supply rail and asserts a fault signal when the voltage drops below a defined threshold. The component operates within a temperature range of -40°C to +85°C and is housed in a compact SOT-23-6 surface-mount package.

Hot Swap Controllers Feature Summary

• Adjustable current limiting with foldback capability to protect against short circuits and inrush events
• Integrated power-fail detection circuitry for monitoring supply voltage integrity
• Soft-start functionality controls turn-on slew rate to minimize bus disturbance
• Compact SOT-23-6 package optimized for space-constrained designs

Hot Swap Controllers Applications

• -48V telecommunications equipment and central office power systems
• Industrial control boards requiring protected power insertion
• Backplane systems with hot-swap capability requirements
• Embedded systems utilizing standard DC power distribution rails

Hot Swap Controllers Procurement Notes

Verify the specific suffix (e.g., BEUT) against the manufacturer's official datasheet to confirm pinout compatibility and thermal characteristics. Ensure the ordering part number matches the exact package type and tape-and-reel specifications required for your assembly process. Cross-reference the RoHS status and environmental compliance data directly from the supplier documentation prior to procurement.

Hot Swap Controllers Selection Notes

Select this controller when designing for -48V or similar positive/negative rail architectures requiring precise inrush management. Evaluate the adjustable current limit range to ensure it accommodates the downstream capacitance and load requirements without nuisance tripping. Confirm that the SOT-23-6 package footprint aligns with existing PCB layout constraints and thermal dissipation capabilities of the target application environment.
