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
