Issue 4 - June 2007

4 When C

has discharged to "zero" (< 80mV) the latch is reset which re-enables the output drive

and allows the device to re-enter soft-start mode.

5 In the event of an overload or short circuit, stages 3 and 4 repeat indefinitely until the fault is

removed.

In the case of a permanent fault damage to the PMOS transistor should not occur because it is
only on for a short part of the overall cycle.

6 The current monitor has an intentional output offset of +150mV. If V

ISET

is held at 0V, the output

of the trip comparator will be permanently high and the output will be completely disabled.
