(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) All voltage values are with respect to GND.
(3) Absolute negative voltage on these terminals is not to go below –0.3 V.
(4) Absolute maximum voltage, withstand 48-V load dump voltage for 400 ms.
(5) Reverse polarity condition: t < 60 s, reverse current < Irev1, GND pin 1-kΩ resistor in parallel with diode.
(6) Test condition: VS = 13.5 V, L = 8 mH, R = 0 Ω, TJ = 150°C. FR4 2s2p board, 2- × 70-μm Cu, 2- × 35-μm Cu. 600-mm2 thermal pad copper area.
