DESCRIPTION (cont.)  
UVLO thresholds for the UC1861/62/65/66 are 16.5V start delay, and the internal system reference.  
(ON) and 10.5V (OFF), whereas the UC1863/64/67/68  
Each device features dual 1 Amp peak totem pole output  
drivers for direct interface to power MOSFETS. The out-  
puts are programmed to alternate in the  
UC1861/63/65/67 devices. The UC1862/64/66/68 out-  
puts operate in unison alllowing a 2 Amp peak current.  
thresholds are 8V (ON) and 7V (OFF). After V  
ex-  
CC  
ceeds the UVLO threshold, a 5V generator is enabled  
which provides bias for the internal circuits and up to  
10mA for external usage.  
A Fault comparator serves to detect fault conditions and  
set a latch while forcing the output drivers low. The Soft-  
Ref pin serves three functions: providing soft start, re-
