ABSOLUTE MAXIMUM RATINGS
When the output current is less than the fault level, the
external output transistor remains switched on. When the
output current exceeds the fault level, but is less than the
maximum sourcing level programmed by IMAX, the out-
put remains switched on, and the fault timer starts to
charge CT, a timing capacitor. Once CT charges to 2.5V,
the output device is turned off and CT is slowly dis-
charged. Once CT is discharged to 0.5V, the IC performs
a retry and the output transistor is switched on again.
The UC3914 offers two distinct reset modes. In one
mode with LR left floating or held low, the IC will repeat-
edly try to reset itself if a fault occurs as described
above. In the second mode with LR held high, once a
fault occurs, the output is latched off until either LR is
toggled low, the part is shutdown then re-enabled using
SD, or the power to the part is turned off and then on
again.
This part is offered in both 18 pin DW Wide-Body (SOIC)
and Dual-In-Line (DIL) packages.
