8 Electrical Ratings
8.1 Absolute Maximum Ratings
Note
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.

Table 211: Absolute Maximum Ratings for TMC8462-BA
*) Stray inductivity of GND and VS connections will lead to ringing of the supply voltage when driving
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 can easily
generate a few volts of ringing leading to temporary voltage overshoot. This should be considered when
working near the maximum voltage.
