Timing Diagrams
The V
4MON
pin is monitored by a comparator to detect an
under-voltage condition. It is designed with 6% hysteresis.
When the V
4MON
input drops below the programmed UV
threshold, the comparator will become active immediately,
indicating a UV condition has occurred. Due to hysteresis,
the V
4MON
input must be brought above the programmed UV
threshold by 6% before the comparator will be in-active,
indicating the UV condition has gone away, See Figure 11.
The V
4MON
comparator is used to control the V
4OUT
pin and
also (in conjunction with a hold timer) to control the RESET
pin.
V
4MON
exhibits typical input resistance of 50KΩ that users
should account the loading effect.
