IS31FL3218 Datasheet 18 CHANNELS LED DRIVER

Manufacturer: ISSI (now Infineon)

Overview: IS31FL3218 18 CHANNELS LED DRIVER April 2012 GENERAL.

General Description

IS31FL3218 is comprised 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 38mA (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.

Key Features

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