Once Vcc rises above the UVLO level, the POWER OK
signal given to the I
interface becomes operative and the SR can be configured
by the main microprocessor. About 400mV of hysteresis is
provided in the UVLO threshold to avoid false triggering of
the Power-On reset circuit.
(I
as (or later than) all other I
valid).
ADDRESS Pin
Connecting this pin to GND forces the chip I
address to 0001000; applying a voltage >2.7V forces the
address to 0001001, as shown below.
