9-Output LED Driver with Intensity Control
and Hot-Insertion Protection
V SUPPLY is the supply voltage used to drive the LED (V).
V LED is the forward voltage of the LED (V).
V OL is the output low voltage of the MAX6964 when
sinking I LED (V).
I LED is the desired operating current of the LED (A).
For example, to operate a 2.2V red LED at 14mA from a
5V supply, R LED = (5 - 2.2 - 0.25) / 0.014 = 182 ? .

than 50mA, like relays and high-current white LEDs, by
paralleling outputs. Use at least one output per 50mA of
load current; for example, a 6V 330mW relay draws
55mA and needs two paralleled outputs to drive it.
Ensure that the paralleled outputs chosen are controlled

by the same blink phase register, i.e., select outputs from

the O0 through O7 range. This way, the paralleled out-
puts are turned on and off together. Do not use output

switched at the same time as any of the other outputs
because it is controlled by a different register.
