IS31FL3236 - 36-CHANNELS LED DRIVER

Datasheet Summary

Description

IS31FL3236 is comprised of 36 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 and independently scaled by a factor of 1, 1/2, 1/3 and 1/4.

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.
  • Each channel can be scaled independently by 1, 1/2, 1/3 and 1/4.
  • -40°C to +85°C temperature range.
  • QFN-44 (5mm × 5mm) and eTQFP-48 package.

IS31FL3236 36 CHANNELS LED DRIVER GENERAL DESCRIPTION IS31FL3236 is comprised of 36 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 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. IS31FL3236 is available in QFN-44 (5mm × 5mm) and eTQFP-48 package. It operates from 2.7V to 5.5V over the temperature range of -40°C to +85°C. October 2021 FEATURES  2.7V to 5.
