Fault on overcurrent, UVLO and thermal shutdown, Note 8
Note 5.
Validated by design, but not production tested.
Note 6.
Pin to Pin total resistance includes lead frame, silicon die metalization, bond wire and FET Rdson resistances. Please be aware that
some manufacturers only specify the Rdson value, which can be significantly less than the total pin to pin resistance.
Note 7.
V
IN
should be within the operating range before the device is enabled.
Note 8.
No error flag out deglitch on UVLO and thermal shutdown.
