• Manufacturer Part Number: MAX1693-MAX1694
• Description: USB Current-Limited Switches with Fault Blanking
• Manufacturer: Maxim

ELECTRICAL CHARACTERISTICS

Note 1: MAX1693’s current limit is tested by forcing V
Note 2: This specification applies to the MAX1693 only. The MAX1694 latches the switch off under a sustained (>10ms) short-
Note 3: Specifications to -40°C are guaranteed by design, not production tested.
