9-Output LED Driver with Intensity Control
and Hot-Insertion Protection
General Description
The MAX6965 I 2 C-compatible serial interfaced periph-
eral provides microprocessors with nine additional out-
put ports. Each output is an open-drain current-sinking
output rated to 50mA at 7V. All outputs are capable of
driving LEDs, or providing logic outputs with external
resistive pullup up to 7V.
Eight-bit PWM current control is also integrated. Four of
the bits are global control and apply to all LED outputs
to provide coarse adjustment of current from fully off to
fully on with 14 intensity steps. Additionally each output
then has an individual 4-bit control, which further
divides the globally set current into 16 more steps.
Alternatively, the current control can be configured as a
single 8-bit control that sets all outputs at once.
Each output has independent blink timing with two blink
phases. LEDs can be individually set to be either on or off
during either blink phase, or to ignore the blink control.
The blink period is controlled by an external clock (up to

be used as a logic control to turn the LEDs on and off, or
as a general-purpose input (GPI).
The MAX6965 supports hot insertion. The SDA, SCL,
RST , BLINK, and the slave address input AD0 remain
high impedance in power-down (V+ = 0V) with up to 6V
