IS32FL3237 - 36-CHANNEL LED DRIVER

General Description

IS32FL3237 is an LED driver with 36 constant current channels.

Each channel can be pulse width modulated (PWM) by 16 bits for smooth LED brightness control.

Key Features

  • 2.7V to 5.5V VCC supply.
  • 1MHz I2C interface, automatic address increment function with readout function.
  • Four selectable I2C addresses.
  • Accurate color rendition - Selectable 8-bit/10-bit/12-bit/16-bit PWM - 8-bit dot correction - 8-bit global current adjust.
  • Open/Short detect function.
  • 62kHz PWM frequency (8-bit PWM).
  • Temperature detect function.
  • EMI/noise reduction technology - Spread spectrum - Selectable Phase Delay - Selectable 180 degree Clock Phase.

IS32FL3237 36-CHANNEL LED DRIVER GENERAL DESCRIPTION IS32FL3237 is an LED driver with 36 constant current channels. Each channel can be pulse width modulated (PWM) by 16 bits for smooth LED brightness control. In addition, each channel has an 8-bit output current control register which allows fine tuning the current for rich RGB color mixing, e.g., a pure white color LED application. The maximum output current of each channel is designed to be 38mA, which can be adjusted by one 8-bit global control register. Proprietary programmable algorithms are used in IS32F3237 to minimize audible noise caused by the MLCC decoupling capacitor. All registers can be programmed via a high speed I2C (1MHz).
