APPLICATIO S I FOR ATIO
The IRF7457’s Thermal Response vs Pulse Duration curve
indicates that the worst-case increase in junction-to-
ambient temperature during a power-cycle for the 3.3V
MOSFET is less than 96 C while the worst-case increase
in junction-to-ambient temperature for the 5V MOSFET is
less than 88 C.
Power MOSFET and Sense Resistor Selection
Tables 7 and 8 list current sense resistors and power
MOSFET transistors, respectively, that can be used with
the LTC4244’s circuit breakers. Table 9 lists supplier web
site addresses for discrete components mentioned
throughout the LTC4244 data sheet.
