MAX6966/MAX6967
10-Port Constant-Current LED Drivers and I/O
Expanders with PWM Intensity Control
Initial Power-Up
On power-up, all control registers are reset ( Table 3).
Power-up status sets I/O ports P0 to P9 high imped-
ance, and puts the device into shutdown mode. This
means that any LED (or other) loads are effectively
turned off, and the MAX6966/MAX6967 start in its low-
est power condition.
PWM Clock
An internal 32kHz oscillator generates PWM timing. If
all output ports are set to static levels, the internal oscil-
Table 3. Initial Power-Up Register Status
lator and PWM logic are disabled automatically, and
the MAX6966/MAX6967 operating current is lowest.
The internal 32kHz oscillator can be replaced by a user
clock up to 100kHz if a precise or synchronized PWM
frequency source is desired. The clock is fed into the
dual-use DOUT/OSC pin, which is switched between a
port output and a clock input using the OSC bit in the
configuration register ( Table 4).
