I/O DESCRIPTION
NAME NO
STAT 1 OUT This is the open drain status output with active low level. An internal comparator drives this output. The pin
is high impedance with ON/BYP = low. With ON/BYP set to high the device and the internal VOUT
comparator becomes active. The active low STAT pin indicates if the DC/DC regulator is settled and the
output voltage above the V
TSTAT
threshold. If not used, this pin can be left open.
