Positive High-Voltage, Hot-Swap Controllers
General Description
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).
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).
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.

Pin Description
PINNAMEFUNCTION
1ON
ON/OFF Control Input. ON is used to implement the undervoltage lockout threshold and resets the part
after a fault condition for the latched-off version (MAX5933A/MAX5933C/MAX5947A, see the Detailed
Description section).
2FB
Power-Good Comparator Input. Connect a resistive divider from output to FB to GND to monitor the output
voltage (see the Power-Good Detection section). FB is also used as a feedback for the current-limit
foldback function.PWRGD/
PWRGD
Open-Drain Power-Good Output. PWRGD is high (PWRGD is low) when VFB is higher than VFBH. PWRGD
is low (PWRGD is high) when VFB is lower than VFBL.GNDGroundTIMERTiming Input. Connect a capacitor from TIMER to GND to program the maximum time the part is allowed to
remain in current limit (see the TIMER section).GATEGate- D r i ve O utp ut. The hi g h- si d e g ate d r i ve for the exter nal N - channel M OS FE T ( see the G ATE V ol tag e secti on) .SENSECurrent-Sense Input. Connect a sense resistor from VCC to SENSE and the drain of the external n-channel
MOSFET.
8VCCPower-Supply Input. Bypass VCC to GND with a 0.1µF capacitor. Input voltage range is from +9V to +80V
for the MAX5947A/B/C. Input voltage range is from +33V to +80V for the MAX5933A–MAX5933F.
