General 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 back-

plane without causing glitches on the backplane

power-supply rail. The MAX5934/MAX5934A feature a

programmable analog foldback current limit, program-

mable undervoltage lockout, and programmable out-

put-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 overtempera-

ture protection.

The MAX5934/MAX5934A operate in the extended

(-40癈 to +85癈) temperature range and are available

in a 16-pin QSOP package.
