17 Absolute Maximum Ratings
The maximum ratings may not be exceeded under any circumstances. Operating the circuit at or near
more than one maximum rating at a time for extended periods shall be avoided by application
design.

*) Stray inductivity of GND and VS connections will lead to ringing of the supply voltage when driving
an inductive load. This ringing results from the fast switching slopes of the driver outputs in
combination with reverse recovery of the body diodes of the output driver MOSFETs. Even small trace
inductivities as well as stray inductivity of sense resistors can easily generate a few volts of ringing
leading to temporary voltage overshoot. This should be considered when working near the maximum
voltage.
