General Description
The MAX5902/MAX5903 are 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 +72V and provide the simplest hot-swap solution by eliminating all external components except the external p-channel MOSFET.
FEATUREs
♦ Wide +9V to +72V Operation
♦ Requires No External Sense Resistor
♦ Drives External p-Channel MOSFET
♦ Limits Inrush Current
♦ Circuit-Breaker Function
♦ Less than 2mA Quiescent Current
♦ ON/OFF Input Permits Load Power-Supply Control and Sequencing
♦ Adjustable Undervoltage Lockout
♦ Power-Good Output with +72V Rating
♦ Latching or Automatic Retry Fault Management
♦ Thermal Shutdown Helps Protect the External MOSFET
♦ Available in Two Small Packages 6-Pin TDFN and SOT23
