8.1 Minimizing I
When the PCA9535 I/Os are used to control LEDs, they are normally connected to V
through a resistor as shown in
off the I/O V
becomes lower than V
Designs needing to minimize current consumption, such as battery power applications,
should consider maintaining the I/O pins greater than or equal to V
Figure 18
than the LED supply voltage by at least 1.2 V. Both of these methods maintain the I/O V
or above V
This concern does not occur in the case of PCA9535C because the I/O pins are
open-drain.
