9-Output LED Driver with Intensity Control
and Hot-Insertion Protection
Global/O8 Intensity Control
The 4 bits used for output O8’s PWM individual intensity
setting also double as the global intensity control
(Table 11). Global intensity simplifies the PWM settings
when the application requires them all to be the same,
such as for backlight applications, by replacing the
nine individual settings with one setting. Global intensi-
ty is enabled with the global intensity flag G in the con-
figuration register (Table 4). When global PWM control
is used, the 4 bits of master intensity and 4 bits of O8
intensity effectively combine to provide an 8-bit, 240-
step intensity control applying to all outputs.
It is not possible to apply global PWM control to a sub-
set of the ports, and use the others as logic outputs. To
mix static logic outputs and PWM outputs, individual
PWM control must be selected (Table 8).
Applications Information
Hot Insertion
The RST input, BLINK input, and serial interface SDA,
SCL, AD0 remain high impedance with up to 6V assert-
ed on them when the MAX6965 is powered down (V+ =
0V). Output ports O0–O8 remain high impedance with
up to 8V asserted on them. The MAX6965 can therefore
be used in hot-swap applications.
Output Level Translation
The open-drain output architecture allows the ports to
level translate the outputs to higher or lower voltages
than the MAX6965 supply. An external pullup resistor
can be used on any output to convert the high-imped-
ance logic-high condition to a positive voltage level.
The resistor can be connected to any voltage up to 7V.
For interfacing CMOS inputs, a pullup resistor value of
220k ? is a good starting point. Use a lower resistance
