Notes:

1. All voltages referenced to SOURCE, T

A = 25 °C.

2. Maximum ratings specified may be applied one at a time without

causing permanent damage to the product. Exposure to Absolute

Maximum Ratings conditions for extended periods of time may

affect product reliability.

3. The absolute maximum rating of the VCC is 17.5 V. This is an

absolute maximum condition that must not be exceeded. Voltages

between the max operating voltage (15 V) and this abs max

rating should be very infrequent and short in duration (e.g. at

start-up or temporary fault conditions). It is not intended as a

guarantee of the reliability of the product up to the absolute

maximum rating, but is a guideline as to the level of applied

voltage above which there is a risk of immediate damage to the

product.

4. Normally limited by internal circuitry. Applies to Controller T

J(C),

MOSFET T

J(M) and Diode Junction Temperature TJ(D).

5. 1/16” from case for 5 seconds.

6. Duration less than 15 ns and I

DS ≤ IOCP(TYP).

Notes:
