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.
