Manufacturer: SI-EN Technolog

Overview: SN3218 18 Channel LED Driver.

This datasheet includes multiple variants, all published together in a single manufacturer document.

Datasheet Details

SN3218 is prised of 18 constant current channels each with independent PWM control, designed for driving LEDs.

The output current of each channel can be set at up to 23mA (Max.) by an external resistor.

The average LED current of each channel can be changed in 256 steps by changing the PWM duty cycle through an I2C interface.

z 2.7V to 5.5V supply z I2C interface, automatic address increment function z Internal reset register z Modulate LED brightness with 256 steps PWM z Each channel can be controlled independently z -40°C to +85°C temperature range z QFN-24 (4mm × 4mm) package.
