6. Low duty cycle pulse techniques are used during test to maintain junction temperature as close to ambient temperature as possible.

7. The VIPK (Sense) Current Limit Sense Voltage is specified at static conditions. In dynamic operation the sensed current turn−off value

depends on comparator response time and di/dt current slope. See the Operating Description section for details.
