MOSFET Thermal Considerations
During normal operation, the external MOSFETs dissi-
pate little power. The MOSFET R
DS(ON)
is low when the
MOSFET is fully enhanced. The power dissipated in nor-
mal operation is P
D
= I
LOAD
2
x R
DS(ON)
. The most
power dissipation occurs during the turn-on and turn-off
transients when the MOSFETs are in their linear regions.
By taking into consideration the worst-case scenario of a
continuous short-circuit fault, consider these two cases:
1) The single turn-on with the device latched after a
fault: MAX5930A/MAX5931A/MAX5931B (LATCH =
high or unconnected).
2) The continuous autoretry after a fault: MAX5930A/
MAX5931A/MAX5931B (LATCH = low).
MOSFET manufacturers typically include the package
thermal resistance from junction to ambient (R
窲A
) and
thermal resistance from junction to case (R
窲C
), which
determine the startup time and the retry duty cycle (d =
t
START
/(t
START
+ t
RETRY
). Calculate the required tran-
sient thermal resistance with the following equation:
