Low-Voltage, Quad, Hot-Swap

Controllers/Power Sequencers

7/–MAX529D

General Description

Features

o Safe Hot Swap for +1V to +15V Power Supplies

The MAX5927A/MAX5929A–MAX5929D +1V to +15V

quad hot-swap controllers provide complete protection

for multisupply systems. They allow the safe insertion

and removal of circuit cards into live backplanes. These

devices hot swap multiple supplies ranging from +1V to

+15V, provided one supply is at or above +2.7V. The

input voltage rails (channels) can be configured to

sequentially turn-on/off, track each other, or have com-

pletely independent operation.

with Any Input Voltage (V

≥ 2.7V)

IN_

o Adjustable Circuit-Breaker/Current-Limit

Threshold from 25mV to 100mV

o Configurable Tracking, Sequencing, or

Independent Operation Modes

o VariableSpeed/BiLevel Circuit-Breaker Response

o Internal Charge Pumps Generate n-Channel

MOSFET Gate Drives

The discharged filter capacitors of the circuit card provide

low impedance to the live backplane. High inrush currents

from the backplane to the circuit card can burn up connec-

tors and components, or momentarily collapse the back-

plane power supply leading to a system reset. The

MAX5927A/MAX5929A–MAX5929D hot-swap controllers

prevent such problems by gradually ramping up the output

voltage and regulating the current to a preset limit when the

board is plugged in, allowing the system to stabilize safely.

After the startup cycle is complete, on-chip comparators

provide VariableSpeed/BiLevel™ protection against short-

circuit and overcurrent faults, and provide immunity against

system noise and load transients. The load is disconnected

in the event of a fault condition. The MAX5929C/

MAX5929D automatically restart after a fault condition,

while the MAX5929A/MAX5929B must be unlatched. The

MAX5927A fault management mode is selectable.

o Inrush Current Regulated at Startup

o Autoretry or Latched Fault Management

o Programmable Undervoltage Lockout

o Status Outputs Indicate Fault/Safe Condition

The MAX5927A/MAX5929A–MAX5929D offer a variety of

options to reduce external component count and design

time. All devices integrate an on-board charge pump to

drive the gates of low-cost external n-channel MOSFETs,

an adjustable startup timer, and an adjustable current

limit. The devices offer integrated features like startup

current regulation and current glitch protection to elimi-

nate external timing resistors and capacitors. The

MAX5929B/MAX5929D provide an open-drain, active-low

status output for each channel, the MAX5929A/

MAX5929C provide an open-drain, active-high status out-

put for each channel, and the MAX5927A status output

polarity is selectable.
