ELECTRICAL CHARACTERISTICS (continued)
(V
Note 1: Specifications to -40°C are guaranteed by design and not production tested.
Note 2: The MAX6399 powers up with the external FET in off mode (V
Note 3: For accurate overtemperature shutdown performance, place the device in close thermal contact with the external MOSFET.
