Compatibility with MAX7311
The MAX7313 is pin compatible and software compatible
with the standard register structure used by MAX7311,
PCA9535, and PCA9555. However, some MAX7311 func-
tions are not implemented in the MAX7313, and the
MAX7313’s PWM and blink functionality is not supported
in the MAX7311. Software compatibility is clearly not
100%, but the MAX7313 was designed so the subset
(omitted) features default to the same power-up behavior
as the MAX7311, PCA9535, and PCA9555, and superset
features do not use existing registers in a different way. In
practice, many applications can use the MAX7313 as a
drop-in replacement for the MAX7311.
Driving LED Loads
When driving LEDs, a resistor in series with the LED
must be used to limit the LED current to no more than
50mA. Choose the resistor value according to the fol-
lowing formula:
RLED = (VSUPPLY - VLED - VOL) / ILED
where:
RLED is the resistance of the resistor in series with the
LED (
).
VSUPPLY is the supply voltage used to drive the LED (V).
VLED is the forward voltage of the LED (V).
VOL is the output low voltage of the MAX7313 when
sinking ILED (V).
ILED is the desired operating current of the LED (A).
For example, to operate a 2.2V red LED at 14mA from a
5V supply, RLED = (5 - 2.2 - 0.25) / 0.014 = 182.
