[1] Voltages with respect to GND.
The bus voltages quoted are DC voltages and are allowed to be exceeded during any negative transient
undershoot that may be generated by normal operation of P82B715, P82B96 or PCA9600 when any of
those parts are driving long PCB traces, wiring or cables. The Lx/Sx pins have internal protective diodes to
GND that will conduct when the applied bus voltage exceeds approximately −0.6 V and these diodes will
limit the amplitude of the negative undershoot. If required, fitting additional Schottky diodes such as
BAT54A at Sx/Sy may be used to further ensure any undershoot at these pins does not cause conduction of
the diodes inside other ICs connected to Sx/Sy.
