36-CHANNEL LED DRIVER

June 2019

GENERAL DESCRIPTION

FEATURES

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.



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 16-bit PWM 256/1024/4096/65536

- 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 6 phase delay

- 180 degree phase delay

-40°C to +125°C temperature range

eTQFP-48 package



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).

IS32F3237 can be turned off with minimum current

consumption by either pulling the SDB pin low or by

using the software shutdown feature.



IS32FL3237 is available in eTQFP-48 package. It

operates from 2.7V to 5.5V over the temperature range

of -40°C to +125°C.

AEC-Q100 Qualified
