Hot Swap Controllers datasheet and documents for MAX5921FESA+
Hot Swap Controllers Overview
The MAX5921FESA+ is a single-channel hot-swap voltage controller designed for safe insertion and removal of circuit cards from live backplanes. It operates within a supply voltage range of -20V to -80V, making it suitable for -48V power systems. The device features an operating supply current of 700 uA and supports a minimum operating temperature of -40°C. It provides programmable current limiting and includes protection mechanisms such as auto-retry, fault timeout, and thermal limiting.
Hot Swap Controllers Feature Summary
- Enables safe hot-plugging of boards into live backplanes
- Offers programmable current limit and circuit breaker functionality
- Integrates overvoltage protection (OVP) and undervoltage lockout (UVLO)
- Includes automatic retry capability and thermal limiting protection
Hot Swap Controllers Applications
- -48V telecommunications power systems
- Live backplane insertion and removal applications
- Circuit card protection in industrial equipment
Hot Swap Controllers Procurement Notes
Verify the exact suffix 'E' indicates the SOIC-8 package and '+' denotes lead-free compliance. Confirm availability status as distribution channels may list limited stock or restricted supply conditions. Ensure the operating environment falls within the specified -40°C to 85°C temperature range and that the input voltage does not exceed the -80V maximum rating.
Hot Swap Controllers Selection Notes
Select this component for applications requiring robust protection during hot-swap events in -48V systems. Consider the 700 uA quiescent current for power-sensitive designs. Verify that the programmable features meet specific system requirements for current limiting and fault response times. Ensure compatibility with the 8-SOIC surface-mount package constraints.
Hot Swap Controllers Part Context
This part belongs to the Maxim Integrated hot-swap controller family, designed for protecting electronic circuits during insertion into powered systems. It addresses the high inrush currents and potential short circuits associated with hot-plugging. The device integrates control logic and power switches to manage power-up sequences safely.
Hot Swap Controllers Replacement Considerations
