MAX4917A Maxim, MAX4917A Datasheet - Page 9

• Manufacturer Part Number: MAX4917A
• Description: The MAX4914B/MAX4915A/B/MAX4917A/B family of switches feature internal current limiting to prevent damage to host devices due to faulty load conditions
• Manufacturer: Maxim

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.
