supply voltage, the operation of the switches with the

autoretry option does not cause problems because the

total power dissipated during the short is scaled by the

duty cycle:

Attention must be given to the MAX4914B/MAX4915B/

MAX4917B (latchoff versions), where the latchoff condi-

tion must be manually reset by toggling ON from high

to low. If the latchoff time duration is not sufficiently

high, it is possible for the device to reach the thermal-

shutdown threshold and never be able to turn the

device on until it cools down.
