Charge pump can sustain maximum 105 V with respect to VB during test pulse 1 for short time (less than 100 μs,

with CPTANK = +40 V e VBP = -65 V).

SENSE and OUT pins can sustain a negative voltage with respect to GND. SENSE and OUT can drop up to 3.6 V

below GND for maximum 100 μs, and up to 4.6 V below GND for maximum 10 μs. This event is sustainable for a

limited number in the life of the device, maximum 10 times.

In case of hot swap turning off, due to High load present, VB line can increase very fast. In this case, the

maximum rating is 70 V for maximum 100 μs. In this condition CPTANK pin can sustain 77 V for less than 100 μs.
