General Description
The MAX5900/MAX5901 are SOT23/TDFN hot-swap controllers that allow a circuit card to be safely hot-plugged into a live backplane without causing a glitch on the power-supply rail. These devices operate from -9V to -100V and provide the simplest hot-swap solution by eliminating all external components except an external n-channel MOSFET.

Features
♦ Wide -9V to -100V Operation
♦ Requires No External Sense Resistor
♦ Drives External N-Channel MOSFET
♦ Limits Inrush Current
♦ Circuit-Breaker Function
♦ Less than 1mA Quiescent Current
♦ ON/OFF Input Permits Load Power-Supply Control and Sequencing
♦ Adjustable Undervoltage Lockout
♦ Power-Good Output with 100V Rating
♦ Latching or Automatic Retry Fault Management
♦ Thermal Shutdown Helps Protect the External MOSFET
♦ Space-Saving 6-Pin SOT23 and TDFN Packages
