Note 1: All devices are 100% production tested at TA = +25°C. Limits over temperature are guaranteed by design.

Note 2: 41.2kΩ is the maximum allowed external resistance value to be connected at the CB pin to GND for safe operation over the

full 2.7V to 18V VIN range. The parameter specified at RCB = 41.2kΩ is guaranteed by bench characterization and correla-

tion, with respect to the tested parameter at RCB = 10.5kΩ. The formula that describes the relationship between RCB and

the circuit-breaker current threshold is: ICB = (RCB/5920) - (VIN/33).

Note 3: The CB resistance can be increased to 46.4kΩ if VIN is between 2.7V and 3.6V, with operating current of 6.6A for no longer

than 500ms. Do not exceed 6A continuous current.

Note 4: Guaranteed by design and not production tested.

Note 5: 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 6: Foldback is active during the startup phase so the internal power MOSFET operates within SOA.

(VIN = VCC = 2.7V to 18V, TA = TJ = -40°C to +105°C, unless otherwise noted. Typical values are at VIN = 12V, RCB = 10.5kΩ, and

TA = +25°C.) (Note 1)
