ELECTRICAL CHARACTERISTICS
Note 1:
Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2:
The LTC4441E/LTC4441E-1 are guaranteed to meet performance
specifications from 0
°
C to 70
°
C. Specifications over the –40
°
C to 85
°
C
operating temperature range are assured by design, characterization and
correlation with statistical process controls. The LTC4441I/LTC4441I-1 are
guaranteed and tested over the –40
°
C to 85
°
C operating temperature
range.
Note 3:
Failure to solder the Exposed Pad of the MSE package to the PC
board will result in a thermal resistance much higher than 38
°
C/W.
Note 4:
Supply current in normal operation is dominated by the current
needed to charge and discharge the external power MOSFET gate. This
current will vary with supply voltage, switching frequency and the external
MOSFETs used.
Note 5:
Rise and fall times are measured using 10% and 90% levels. Delay
times are measured from 50% of input to 20%/80% levels at driver
output.
Note 6:
Blanking time is measured from 50% of OUT leading edge to 10%
of BLANK with a 1k
pull-up at BLANK pin. LTC4441 only.
Note 7:
Guaranteed by design, not subject to test.
Note 8:
This IC includes overtemperature protection that is intended to
protect the device during momentary overload conditions. The junction
temperature will exceed 125
°
C when overtemperature protection is active.
Continuous operation above the maximum operating junction temperature
may impair device reliability.
