Overview
The IS32FL3740-ZLA3-TR is a linear LED driver IC manufactured by Lumissil Microsystems, designed for dot matrix LED display applications. It features four constant current outputs capable of delivering up to 84 mA per channel. The device operates within an input voltage range of 5 V to 28 V and supports PWM dimming control. Packaged in a compact 20-pin eTSSOP (6.5mm x 6.4mm) format, it is supplied in tape and reel configurations suitable for automated surface-mount assembly.
Feature Summary
- Integrated linear regulation with four independent constant current channels for precise LED brightness control
- Supports pulse-width modulation (PWM) dimming for smooth intensity adjustment without color shift
- Compact 20-pin eTSSOP package optimized for space-constrained dot matrix display designs
Applications
- Dot matrix LED displays
- Automotive interior lighting indicators
- Industrial status panels
Procurement Notes
Verify the specific suffix ZLA3-TR against official Lumissil documentation to confirm packaging quantity and moisture sensitivity level requirements. Ensure the ordering unit matches the manufacturer's specified reel size. Cross-reference the datasheet revision date to validate compatibility with your design specifications before finalizing procurement.
Selection Notes
Select this component when designing systems requiring multi-channel linear LED driving with integrated PWM dimming capabilities. The 84 mA output current suits standard indicator LEDs, while the wide supply voltage range accommodates various automotive and industrial power rails. Evaluate thermal performance based on the total power dissipation across all active channels within the eTSSOP-20 footprint.
Part Context
This part belongs to Lumissil’s IS32FL series of LED display drivers, which focus on high-density matrix applications. Unlike general-purpose lighting controllers, these devices are engineered specifically for pixelated displays, offering simplified interface requirements and robust current matching across multiple channels for uniform visual output.
Replacement Considerations
No public substitute part numbers are confirmed for this specific model. Designers should consult Lumissil directly for potential obsolescence management or pin-compatible alternatives if supply constraints arise.
