IS31FL3236-TQLS2

Overview

The IS31FL3236-TQLS2 is a 36-channel LED driver IC manufactured by Lumissil Microsystems. It features independent PWM control for each channel and operates within a supply voltage range of 2.7 V to 5.5 V. The device supports an I2C interface with a maximum frequency of 400 kHz. Each output channel provides a constant current of 38 mA. The component is housed in an ETQFP-48 package and is rated for operation between -40°C and +85°C.

Feature Summary

Provides 36 independent constant current channels for precise LED driving
Integrates individual PWM control for each output channel
Utilizes I2C communication interface for system control

Applications

LED lighting systems requiring multi-channel control
Display backlighting applications
General-purpose LED indicator arrays

Procurement Notes

Verify the specific suffix TQLS2 against official Lumissil documentation to confirm package type and tape/reel specifications. Confirm lifecycle status, as this part may be marked NRND (Not Recommended for New Designs). Ensure compatibility with existing PCB footprints for the ETQFP-48 package before procurement.

Selection Notes

Select this component when a high channel count is required in a compact form factor. The ETQFP-48 package offers a balance of pin density and thermal performance. Verify that the 38 mA per channel output current meets the requirements of the connected LEDs. Ensure the host controller supports the necessary I2C protocol for configuration.

Part Context

The IS31FL3236 belongs to Lumissil's IS31FL series of LED drivers. This series focuses on providing integrated solutions for managing multiple LED outputs with minimal external components. The family typically includes variants with different channel counts and package options to suit various display and lighting design constraints.

Replacement Considerations

Check for direct substitutes within the IS31FL3236A or IS31FL3235 families if available. Verify pinout compatibility and electrical parameter alignment before substituting. Consult Lumissil official documentation for approved alternative part numbers.
