Hot Swap Controllers datasheet and documents for MAX5903LBEUT+T
Hot Swap Controllers Overview
The MAX5903LBEUT+T is a hot-swap voltage controller designed for safe insertion of circuit cards into live backplanes. It operates within a supply voltage range of +9V to +72V and features adjustable current limiting with a single channel configuration. The device draws a typical operating supply current of 1 mA and functions reliably across an extended temperature range from -40°C to +85°C. Packaged in a compact SOT-23-6 surface-mount format, it eliminates the need for external components other than the p-channel MOSFET.
Hot Swap Controllers Feature Summary
- Provides simple hot-swap solution by eliminating external components except the external p-channel MOSFET
- Limits inrush current to the load during startup
- Offers circuit-breaker function for overcurrent protection
- Prevents glitches on the power-supply rail during card insertion
Hot Swap Controllers Applications
- Hot plugging circuit cards into live backplanes
- Power supply sequencing improvements
- Overcurrent protection in high-voltage systems
Hot Swap Controllers Procurement Notes
Verify component authenticity through authorized Analog Devices or Maxim Integrated distributors. Confirm RoHS compliance status via official datasheets. Check current availability as Mouser indicates limited supply. Ensure ordering suffix matches required package type. Validate revision history against latest manufacturer documentation.
Hot Swap Controllers Selection Notes
Select this controller when designing systems requiring robust hot-swap capabilities without complex external circuitry. Suitable for applications needing adjustable current limiting and overcurrent protection. Consider the SOT-23-6 package for space-constrained designs. Verify compatibility with external p-channel MOSFET selection for optimal performance.
Hot Swap Controllers Part Context
Part of the Simple Swapper family, the MAX5903 series simplifies hot-swap design by integrating control logic directly. It complements similar models like MAX5902 and MAX5903 variants, offering consistent functionality across different package options including TDFN and SOT-23 formats for flexible board layout considerations.
Hot Swap Controllers Replacement Considerations
MAX5902 serves as a functional alternative within the same family. Cross-reference pinouts and electrical specifications before substitution. Verify package compatibility and thermal characteristics match original design requirements.
