APPLICATIONS INFORMATION
Choosing the CT Capacitor
The CT capacitor may be used to program the timing
parameters associated with the pushbutton. For a given
CT capacitor the timing parameters may be calculated as
below. CT is in units of μF.
tONB_LO = 5000 × CT ms
tPBSTAT_PW = 5000 × CT ms
tONB_WAKE = 40000 × CT ms
tWAKE_ON = 500 × CT seconds
tONB_HR = 500 × CT seconds
tHR = 100 × CT seconds
Programming the UVOT Register
The UV/OT warning byte (default 0000 0000) structure
is as below:
BIT7
BIT6
BIT5
BIT4
BIT3
BIT2
BIT1
BIT0
RESET_ALL
UV[2]
UV[1]
UV[0]

Programming the RSTB and IRQB Mask Registers
The RSTB mask register can be programmed by the user
at sub-address 0Ah and its format is as below.
If a bit is set to ‘0,’ then the corresponding regulator’s
PGOOD will pull RSTB low if a PGOOD fault were to occur.
The default for this register is FFh.
The IRQB mask register has the same bit format as the
RSTB mask register. The IRQB mask register is located at
sub-address 0Bh and its default contents are 00h.
PGOOD7 is used only when the LED driver is congured
as a high voltage boost regulator.
