Positive High-Voltage, Hot-Swap Controllers

General Description

Features

The MAX5933A–MAX5933F/MAX5947A/B/C fully integrat-

ed hot-swap controllers for +9V to +80V positive supply

rails (MAX5947A/B/C), allow for the safe insertion and

removal of circuit cards into live backplanes without caus-

ing glitches on the backplane power-supply rail. The

MAX5947B is pin- and function-compatible with the

LT1641-2. The other devices offer added features such

as a choice of active-high or active-low power-good out-

puts (PWRGD/PWRGD), latched/autoretry fault manage-

ment, and autoretry duty-cycle options of 3.75% or 0.94%

(see the Selector Guide).

♦ Pin- and Function-Compatible with the LT1641-2

(MAX5947B)

♦ Provides Safe Hot Swap for +9V to +80V Power-

Supply Range (MAX5947A/B/C)

♦ Safe Board Insertion and Removal from Live

Backplanes

♦ Latched/Autoretry Management

♦ Active-Low or Active-High Power-Good Output

♦ Programmable Foldback Current Limiting

♦ High-Side Drive for an External N-Channel MOSFET

♦ Built-In Thermal Shutdown

The MAX5933A–MAX5933F are available with a default

undervoltage lockout threshold of +31V and operate over

a supply voltage range of +33V to +80V. The

MAX5947A/B/C are available with a default undervoltage

of +8.3V. All devices feature a programmable analog

foldback current limit. If the device remains in current limit

for more than a programmable time, the external

n-channel MOSFET is either latched off (MAX5933A/

MAX5933C/MAX5947A) or is set to automatically restart

after a timeout delay (MAX5933B/MAX5933D/MAX5933E/

MAX5933F/MAX5947B/MAX5947C).

♦ Undervoltage Lockout (UVLO)

♦ Overvoltage Protection

♦ User-Programmable Supply Voltage

Power-Up Rate

Ordering Information

The MAX5933_ and MAX5947_ operate in the extended

temperature range of -40°C to +85°C. These devices are

available in an 8-pin SO package.
