MAX6966/MAX6967
10-Port Constant-Current LED Drivers and I/O
Expanders with PWM Intensity Control
In run mode, the output port goes low, approaching 0V,
as the port’s static constant current saturates trying to
sink a higher current than the 220k ? pullup resistor
can source.
In shutdown mode, the output goes high impedance
together with any other constant-current outputs. This
output remains low during ramp-up and fade-down
sequences because the current drawn by the 220k ?
pullup resistor is much smaller than the available output
constant current, even at the lowest fade current step.
Driving Load Currents Higher than 20mA
The MAX6966/MAX6967 can be used to drive loads
needing more than 20mA, like high-current white LEDs,
by paralleling outputs. For example, consider a white
LED that needs to be driven with 70mA. This LED can
be driven using ports P0, P1, P2, and P3 connected in
parallel (shorted together). Three of the ports should be
configured for full current (20mA), and the last port
should be configured for half current (10mA) to meet
the 70mA requirement. The four ports can be controlled
simultaneously with one write access using register
0x0B ( Table 6). Note that because the output ports
have current limiting, they do not have to be switched
simultaneously to ensure safe current sharing.
Power-Supply Considerations
The MAX6966/MAX6967 operate with a power-supply
voltage of 2.25V to 3.6V. Bypass the power supply to
GND with a 0.1μF ceramic capacitor as close to the
device as possible. For the TQFN version, connect the
underside exposed pad to GND.
