Description

The MAX5934/MAX5934A are fully integrated hot-swap controllers for +9V to +80V (MAX5934A) positive supply rails. The MAX5934 is optimized for +33V to +80V power-supply rails. These devices allow for the safe insertion and removal of circuit cards into a live backplane without causing glitches on the backplane power-supply rail. The MAX5934/MAX5934A feature a programmable analog foldback current limit, programmable undervoltage lockout, and programmable output- voltage slew rate through an external n-channel MOSFET. In addition, if these devices remain in current limit for more than a programmable time, the external n-channel MOSFET latches off. The MAX5934/MAX5934A feature pin-selectable PWRGD_ assertion polarity (active low or active high) and pin-selectable fault management (latched or autoretry). Other features include automatic restart after a circuit-breaker fault, selectable duty-cycle (DC) options, and thermal-shutdown mode for overtemperature protection. The MAX5934/MAX5934A operate in the extended (-40°C to +85°C) temperature range and are available in a 16-pin QSOP package.
