DESCRIPTION
The CAT9552 is a 16-channel, parallel input/output
port expander optimized for LED On/Off and blinking
control. Each individual LED may be turned ON, OFF,
or set to blinking at one of two programmable rates.
The CAT9552 is compatible with I
applications where it is desireable to limit the bus
traffic or free-up the bus master’s internal timer. Three
address pins allow up to eight CAT9552 devices to
occupy the same bus.
The CAT9552 contains an internal oscillator and two
PWM signals, which drive the LED outputs. The user
may program the period and duty cycle for each
individual PWM signal. After an initial set-up command
to program the Blink Rate 1 and Blink Rate 2 (frequency
and duty cycle), only one command from the bus master
is required to turn each individual open drain output ON,
OFF, or cycle at Blink Rate 1 or Blink Rate 2. Each open
drain LED output can sink a maximum current of 25mA.
The total continuous current sunk by all I/Os must not
exceed 200mA per package.
