IS32FL3236A
IS32FL3236A is 36-CHANNEL LED DRIVER manufactured by Lumissil.
DESCRIPTION
IS32FL3236A is prised of 36 constant current channels each with independent PWM control, designed for driving LEDs, PWM frequency can be 3k Hz or 22k Hz. The output current of each channel can be set at up to 38m A (Max.) by an external resistor and independently scaled by a factor of 1, 1/2, 1/3 and 1/4. The average LED current of each channel can be changed in 256 steps by changing the PWM duty cycle through an I2C interface.
The chip can be turned off by pulling the SDB pin low or by using the software shutdown feature to reduce power consumption.
IS32FL3236A is available in e TQFP-48 package. It operates from 2.7V to 5.5V over the temperature range of -40°C to +125°C.
