slave attempts to respond, bus arbitration rules apply,
with the lowest address code going first. The other
device(s) will not generate an acknowledge and will
continue to hold the
ALERT
pin low until it is allowed to
clear its own interrupt.
Clearing the interrupt has no effect on the state of the
status registers.
Input/Output Pins
Each IO_ pin is protected by an internal 20mA (typical)
current-limit circuit. Typical pull-down on-resistance at
V
CC
= +2.7V and +5.5V is 100
and 66
, respectively.
When the IO_ is high impedance, it actually has a
0.5μA pull-down current source included as part of the
read-back functionality.
External pull-up resistors and IO_ sink capability can
affect the outputs’ rise and fall times. When using the
MAX1608/MAX1609 to control an external MOSFET in
power-switching applications, pull-up and/or series resis-
tance can be used together with the MOSFET’s gate
capacitance or additional external capacitance (Figure 6)
to control the transition time of the switched source.
The input logic levels are TTL compatible and are sam-
pled during a readback SMBus transmission (see RSB
register in
Data Registers
section ).
Power-On Reset
The MAX1608/MAX1609’s power-on-reset circuit
ensures that the IO_ states are defined when V+ is first
applied or when the supply dips below the UVLO
