ELECTRICAL CHARACTERISTICS

according to the following formula:

Note 6: Switch on-resistance is guaranteed by correlation to wafer level

measurements.

Note 7: 4MHz operation is guaranteed by design but not production tested

and is subject to duty cycle limitations (see Applications Information).

Note 8: This IC includes overtemperature protection that is intended to

protect the device during momentary overload conditions. Junction

temperature will exceed 125

°C when overtemperature protection is active.

Continuous operation above the specified maximum operating junction

temperature may impair device reliability.
