The MAX6965 I

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

1kHz) on BLINK or by a register. The BLINK input can also

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

asserted upon them. The output ports remain high

impedance with up to 8V asserted upon them.

The MAX6965 is controlled through a 2-wire I

interface, and can be configured to one of four I

addresses.
