ABSOLUTE MAXIMUM RATINGSFor externally applied voltages or currents exceeding these limits damage of the device may occur!
All pins of the IC are protected against ESD. The verification is performed according to MIL883C, human body
model with R=1.5kΩ, C=100pF and discharge voltage ±2kV, corresponding to a maximum discharge energy of
0.2mJ.

THERMAL DATA see application note 110 for SO packages.
ELECTRICAL CHARACTERISTCS (8V < VVS < 20V, VEN = HIGH, -40°C ≤ TJ ≤ 150°C, unless otherwise spec-ified. The voltages are refered to GND and currents are assumed positive, when current flows into the pin.
