MAX5947BESA+T

Hot Swap Controllers Overview

The MAX5947BESA+T is a positive high-voltage hot-swap controller designed for safe insertion and removal of circuit boards in live backplanes. It supports input voltages from -80V to -20V and features an internal N-channel switch. Key electrical parameters include a single channel configuration, operation within a temperature range of -40°C to +85°C, and availability in an 8-pin SOIC-Narrow package. The device integrates protection mechanisms such as overvoltage protection (OVP), undervoltage lockout (UVLO), fault timeout, and auto-retry capabilities.

Hot Swap Controllers Feature Summary

• Manages safe insertion and removal of circuit boards in live backplane environments
• Integrates overvoltage protection, undervoltage lockout, and fault timeout logic
• Supports automatic retry functionality following fault conditions

Hot Swap Controllers Applications

• Live backplane system board insertion and removal
• Industrial automation control modules
• Embedded systems requiring high-voltage power management

Hot Swap Controllers Procurement Notes

Verify the specific suffix (+T) indicates tape-and-reel packaging when sourcing. Confirm the manufacturer designation as Analog Devices Inc. or Maxim Integrated, as Maxim was acquired by ADI. Ensure the component meets RoHS compliance requirements if specified for your project. Cross-reference the Mouser part number 700-MAX5947BESA+T for accurate distributor identification and current availability status.

Hot Swap Controllers Selection Notes

Select this component for applications requiring robust protection against inrush currents and voltage spikes during board insertion. It is suitable for negative voltage systems ranging from -20V to -80V. Consider the 8-SOIC package size for space-constrained designs. Verify that the integrated N-channel switch meets the current requirements of the load without external components.

Hot Swap Controllers Part Context

This component belongs to the Maxim Integrated hot-swap controller family, now under Analog Devices. It is functionally related to other controllers like the MAX5937 and MAX5948, which offer similar protection features for different voltage ranges or configurations. These devices are commonly used in telecommunications and industrial equipment to prevent damage during maintenance or expansion.

Hot Swap Controllers Replacement Considerations

Public confirmed substitute part numbers include MAX5948BESA+ and MAX5937LNESA+T. Verify pin compatibility and voltage range specifications before substitution. The MAX5948 offers similar hot-swap control features but may differ in specific voltage thresholds or package options.
