LX24132ILQ-TR

LED Driver IC Overview

The LX24132ILQ-TR is a 32-channel LED driver IC manufactured by Microsemi Corporation. It features an integrated shift register and PWM dimming capability, supporting up to 200mA output current per channel. The device is housed in a 56-pin QFN (8x8 mm) package. It is designed for low-voltage display backlight applications, offering precise control for LCD panels through serial interface communication.

LED Driver IC Feature Summary

• Integrates 32 independent LED driver channels with built-in shift register functionality
• Supports high-resolution PWM dimming for uniform brightness control across all outputs
• Optimized for low-voltage operation in portable and compact display systems

LED Driver IC Applications

• LCD panel backlighting for mobile devices
• Display modules requiring multi-channel LED control
• Portable electronics with space-constrained PCB layouts

LED Driver IC Procurement Notes

Verify the exact suffix 'TR' indicates tape-and-reel packaging when sourcing. Confirm the manufacturer is Microsemi Corporation or its successor entities, as corporate structures may have changed. Ensure the 56-QFN package dimensions match your board design constraints before finalizing procurement orders.

LED Driver IC Selection Notes

Select this component when a single IC must drive 32 LEDs with individual PWM control. It is suitable for designs prioritizing reduced component count and simplified serial interfacing over discrete driver solutions. Consider the 200mA limit per channel against total load requirements.

LED Driver IC Part Context

This part belongs to Microsemi's LED driver family, specifically tailored for display backlighting. It replaces older discrete driver arrays, integrating control logic and power stages into a compact form factor. The series supports various display sizes common in consumer electronics.

LED Driver IC Replacement Considerations

Check for direct pin-compatible alternatives from Microsemi or other manufacturers if supply is limited. Verify that substitute parts maintain the 32-channel count and 56-QFN footprint to ensure mechanical compatibility without redesigning the PCB.

LED Driver IC FAQ

What is the maximum output current per channel?

The LX24132ILQ-TR supports a maximum output current of 200mA per channel.

How is the dimming controlled?

Dimming is achieved through integrated PWM (Pulse Width Modulation) signals managed via the internal shift register.
