ELECTRICAL CHARACTERISTICS (continued)

Note 3: 40.2kω is the maximum allowed external resistance value to be connected at CB pin to GND for safe operation. All devic-

Note 4: The current-limit slow-comparator response time is weighed against the amount of overcurrent so the higher the

overcurrent condition, the faster the response time.

Note 5: Foldback is active during the startup phase so the internal power MOSFET operates within SOA.
