NAME
HSOK
FUNCTION
Hot-Swap OK (MAX5042 Only). HSOK ’s open-drain output is forced to NEGIN upon
hot-swap completion.
Hot-Swap Enable (MAX5042 Only). HSEN is the center point of the internal hot-swap

UVLO divider. Use an external voltage-divider or a 100k ? pullup resistor to the most
positive rail to override.
Negative Supply Input (MAX5042 Only). NEGIN connects to the most negative input

NEGIN
supply rail. NEGIN provides the hot-swap circuit’s most negative connection. NEGIN
is at the same potential as the IC substrate.

PWMNEG
Hot-Swap Gate (MAX5042 Only). Connect HSGATE to the gate of the external hot-
swap MOSFET.
Hot-Swap MOSFET Drain Sense (MAX5042 Only). Connect HSDRAIN to the drain of
the external hot-swap MOSFET.
Current-Sense Amplifier Output. The amplifier has a gain of 10. Connect CSOUT to
RAMP for current-mode control.
Positive Current-Sense Connection. Place the current-sense resistor as close as
possible to the device and use a Kelvin connection.
Negative Current-Sense Connection. Place the current-sense resistor as close as
possible to the device and use a Kelvin connection.
Analog Signal Return for the PWM Section
Driver Delay Adjust Connection. Connect a resistor and a 0.22μF capacitor from
DRVDEL to PWMNEG. The resistor at DRVDEL controls the skew between the
36

DRVDEL
PPWM signal and the power pulse applied to the internal power MOSFETs. Use in
conjunction with a secondary-side synchronous-rectifier controller. The skew allows
for the optimization of the synchronous-rectifier drive pulse.

PPWM
REG9

REG15
PWM Pulse Output. PPWM leads the internal power MOSFET pulse by an amount
determined with the resistor value at DRVDEL.
9V Internal Regulator Output. Use primarily as a source for the internal gate drivers.
Bypass REG9 to PWMNEG with a 1μF ceramic capacitor.
5V Internal Regulator Output. Bypass REG5 to PWMNEG with a 1μF ceramic
capacitor.
15V Startup Regulator Output. A voltage greater than 18V on REG15 disables the
regulator. Bypass REG15 to PWMNEG with at least one 1μF ceramic capacitor.
PWM Undervoltage Lockout. UVLO is the center point of the PWM undervoltage
46

UVLO
lockout divider. Use an external divider or a 100k ? pullup resistor to POSINPWM to
override. Connect the external resistor-divider network from POSINPWM to
PWMNEG.
