IS31FL3193D-CLS2-TR

Overview

The IS31FL3193D-CLS2-TR is a 3-channel FxLED driver IC manufactured by Lumissil Microsystems. It operates within an input voltage range of 2.7 V to 5.5 V and supports I2C communication at frequencies up to 400 kHz. The device delivers output currents up to 42 mA per channel and is housed in an 8-pin WLCSP package with dimensions of 1.6 mm x 1.0 mm. It functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates three independent LED drive channels for compact lighting control
• Supports I2C interface for efficient digital control and data transmission
• Utilizes ultra-thin WLCSP packaging to minimize board space requirements

Applications

• Compact portable electronic devices requiring minimal footprint
• Automotive interior ambient lighting systems
• Industrial indicator and signaling applications

Procurement Notes

Verify the specific suffix CLS2 against the manufacturer's current datasheet to confirm pinout and electrical characteristics, as variations may exist. Confirm RoHS compliance status directly with the supplier documentation before integration into regulated products.

Selection Notes

Select this component when system constraints demand a small form factor alongside multi-channel LED driving capabilities. Ensure the host controller supports I2C protocols and that the available PCB area accommodates the 1.6 mm x 1.0 mm WLCSP package dimensions effectively.

Part Context

This part belongs to the IS31FL31xx series of FxLED drivers designed for high-density lighting applications. It complements larger channel-count drivers by providing a specialized solution for low-channel requirements where size and weight are critical design parameters.

Replacement Considerations
