MAX4787 Maxim, MAX4787 Datasheet - Page 3

• Manufacturer Part Number: MAX4787
• Description: The MAX4785-MAX4788 family of switches feature internal current limiting to prevent host devices from being damaged due to faulty load conditions
• Manufacturer: Maxim

ELECTRICAL CHARACTERISTICS (continued)
(V
Note 1: All parts are 100% tested at +25°C. Limits across the full temperature range are guaranteed by design and correlation.
Note 2: Latch-off current does not include the current flowing into FLAG.
Note 3: The on-time is defined as the time taken for the current through the switch to go from 0mA to full load. The off-time is defined
Note 4: Retry time is typically 7x the blanking time.
