Comparators
Two CMOS comparators are available to perform protection schemes.
Short pulses (
has a threshold of 0.6 V (typical value) forces the device in a latched shut down state (e.g.
LVG low, HVG low, oscillator stopped), as in the under voltage conditions. Normal operating
conditions are resumed after a power-off power-on sequence. The EN2 input (active high),
with a threshold of 1.2 V (typical value) restarts a Soft Start sequence (see timing
diagrams). In addition the EN2 comparator, when activated, removes a latched shutdown
caused by EN1.
