With patented features to prevent distracting artefacts in “color-chasing” or “deep breathing” LED animation effects, the STMicroelectronics LED1202 12-channel LED driver enables smoother and more natural interactions with smart-home devices, wearable electronics, and small appliances.
The LED1202 can store eight programmable patterns and sequences and operate independently of the main controller, enabling the host system to save power while sophisticated lighting effects run continuously. 12-bit internal PWM dimming enables precision control of programmed sequences and the main controller can set 8-bit values for analog dimming via the driver’s I2C interface. Minimal external components are required to complete the driver circuit.
With 12 output channels, a single LED1202 can drive four RGB LEDs at up to 20mA per channel. An innovative synchronization feature allows connecting up to eight LED1202 drivers to control larger LED arrays (more info).
