ISL6425
Once Vcc rises above the UVLO level, the POWER OK
signal given to the I 2 C interface block will be HIGH, the I 2 C
interface becomes operative and the SR can be configured

provided in the UVLO threshold to avoid false triggering of

the Power-On reset circuit.
(I 2 C comes up with EN = 0, EN goes HIGH at the same time
as (or later than) all other I 2 C data for the PWM becomes
valid).

ADDRESS Pin
Connecting this pin to GND forces the chip I 2 C interface
address to 0001000; applying a voltage >2.7V forces the
address to 0001001, as shown below.
