MAX5934AEEE+
Positive High-Voltage, Hot-Swap Controllers with Selectable Fault Management and Status Polarity
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°C to +85°C) temperature range and are available
in a 16-pin QSOP package.

Pin Description
PINNAMEFUNCTIONLATCH/
RETRY
Circuit-Breaker Fault-Management Select Input. Connect LATCH/RETRY to GND to latch off after a circuit-
breaker fault. Leave LATCH/RETRY open or drive to logic-high voltage for automatic restart after a circuit-
breaker fault.
2ONOn/Off Control Input. ON implements the undervoltage-lockout threshold and resets the part after a fault
latch (see the Fault Management (LATCH/RETRY) section).POL_SELPWRGD_ Polarity Select Input. Leave POL_SEL open or drive to logic-high voltage for PWRGD_ asserted
high. Connect POL_SEL to GND for PWRGD_ asserted low.FB1
Power-Good Comparator Input. Connect a resistive divider between output, FB1, and GND to monitor the
output voltage (see the Power-Good (PWRGD_ ) Detection section). FB1 is also used as feedback for the
current-limit foldback function.PWRGD2
Open-Drain Power-Good Output. POL_SEL determines the output polarity of PWRGD2. PWRGD2 is
asserted when FB2 is higher than VFB2H. PWRGD2 deasserts when FB2 is lower than VFB2L (see the
Power-Good (PWRGD_) Detection section).PWRGD1
Open-Drain Power-Good Output. POL_SEL determines the output polarity of PWRGD1. PWRGD1 is
asserted when FB1 is higher than VFB1H. PWRGD1 deasserts when FB1 is lower than VFB1L (see the
Power-Good (PWRGD_) Detection section).PWRGD3
Open-Drain Power-Good Output. POL_SEL determines the output polarity of PWRGD3. PWRGD3 asserts
when GATE is at maximum voltage. PWRGD3 deasserts after the timeout following an overcurrent event
(see the Power-Good (PWRGD_) Detection section).GNDGroundOUTOutput Voltage. OUT is used as the return path for the internal GATE protection clamping circuitry.TIMERTiming 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-Drive Output. The high-side gate drive for the external n-channel MOSFET (see the GATE section).FB2Noninverting Comparator Input. FB2 is used to monitor any other voltage in the system. When FB2 rises
higher than VFB2H, PWRGD2 asserts. When FB2 drops below VFB2L, PWRGD2 deasserts.N.C.No Connection. Not internally connected.SENSECurrent-Sense Input. Connect a sense resistor from VCC to SENSE and the drain of the external n-channel
MOSFET.DCDuty-Cycle Select. When DC is floating, the default duty cycle is 3.75%. Connect DC to VCC to set the duty
cycle to 1.88%. Connect DC to GND to set the duty cycle to 0.94%.VCCPower-Supply Input. Bypass VCC to GND with a 0.1µF capacitor. The input voltage range is from +9V to
+80V for the MAX5934A and +33V to +80V for the MAX5934.
