The IS31FL3236A-QFLS2-TR is a versatile 36-channel LED driver IC manufactured by Lumissil Microsystems. Designed for driving LEDs, it offers independent PWM control for each channel and supports selectable PWM frequencies of 3kHz or 22kHz. The output current for each channel can be set up to a maximum of 38mA using an external resistor and can be independently scaled by factors of 1, 1/2, 1/3, and 1/4. The average LED current is adjustable in 256 steps via the I2C interface.
This LED driver operates within a supply voltage range of 2.7V to 5.5V. It is available in a QFN-44 package and is suitable for applications requiring precise LED brightness modulation. The chip can be powered down using a software shutdown feature or by pulling the SDB pin low to conserve power. It is designed for operation across industrial temperature ranges, with specific variants available for -40°C to +85°C and -40°C to +125°C.
Key features include an I2C interface with automatic address increment and four selectable I2C addresses. The IS31FL3236A-QFLS2-TR is RoHS and Halogen-Free compliant, making it suitable for a wide range of electronic devices, including hand-held devices with LED displays and LED lighting in home appliances.
