MAX5903ACEUT+T is a high accuracy Hot Swap™ controller for applications that require maximum fault protection and precise power sequencing for card inserts and removals. The Hot Swap controller provides up to 12A of inrush current limiting of ground-referenced loads, adjustable foldback current limiting to prevent overloading, accurate supply-voltage margining, and user-programmable control of thermal protection, fault-recovery, and sequencing-timing sequences. By combining a unique combination of features, the MAX5903ACEUT+T offers superior protection while providing a high degree of flexibility in implementing advanced fault-recovery, sequencing and thermal protection schemes.
Features of MAX5903ACEUT+T include:
- Soft-Start inrush current limiting with foldback current limiting
- Dual-channel, user-programmable fault protection
- Flexible programmable fault-recovery, sequencing and thermal protection
- Supply-voltage margining with configurable margin levels
- Undervoltage lockout (UVLO) for power-on sequencing
- Supports active hot-insertion/removal
The MAX5903ACEUT+T is typically used to protect sensitive components during card insertion and removal from a backplane. The controller is well suited for hot-swap applications involving 12A loads, and can be used for open-circuit and short-circuit protection, power-up/down sequencing, undervoltage and overvoltage protection, thermal protection, and other fault protection schemes. In addition, the controller supports programmable power-on sequencing of multiple loads, and features advanced features such as adjustable overcurrent foldback modes, adjustable margin levels, and configurable fault-recovery schemes. The controller is an ideal choice for small form factor, high port-count systems such as blade servers and network switches, where maximum system uptime is crucial.
The MAX5903ACEUT+T Hot Swap controller works by monitoring the voltage of the main system power inputs. The controller provides programmable switching on/off of the loads and linearly reduces the inrush current of the load on power-up. Additionally, the controller maintains a soft start to programmable voltage levels to limit inrush current while charging filter capacitors. This ensures that the power supply is not overloaded. The controller also monitors the output voltage and shuts off the load if the voltage exceeds the programmable overvoltage threshold. The voltage also trips the overvoltage protection of the power supply if necessary.
The MAX5903ACEUT+T controller is designed to be flexible in order to cover a wide range of supply-voltage and current protection schemes. The controller can be programmed to control the power-on sequencing for multiple supplies and enable user-defined margin levels for power-on, sequencing and load activation. In addition, the controller provides user-programmable inrush limit, overcurrent limit, and fault protection. The controller also supports active hot insertion/removal and is well suited for applications that require more advanced fault-recovery, sequencing, and thermal protection schemes.
Overall, the MAX5903ACEUT+T Hot Swap controller provides a complete power-up, power-down and power-monitoring solution that is both reliable and customizable. The controller provides users with maximum fault protection and precise power sequencing for all Hot Swap applications. Furthermore, with its wide range of features and flexibility, the MAX5903ACEUT+T is an excellent choice for medical, industrial, and consumer hot-swap applications.
