Greetings folks -
I could use an LED driver that drives up to 9 individual LEDs (3 RGB chips, probably). One that pretty much does what I would like is the TI LP55231. It uses I2C interface, uses PWM current control individually, and has a programmable sequencer for different flash patterns.
What I am looking for are alternatives to this device. It does not need to match feature by feature but that has a similar feature set would be really helpful. Low shut-down current is essential. Cost is an important factor. It would be nice to NOT have it in a leadless package.
The idea is to drive 9 LEDs, 3 red, 3 green, 3 blue and offload the management from the MCU. Minimum would be 6 channels, 3 red and 3 green.
