IS32BL3552-ZLA3

Overview

The IS32BL3552-ZLA3 is a boost-type LED driver IC manufactured by Lumissil Microsystems. It features two-channel current source output with a maximum output current of 360 mA per channel. The device operates within an input voltage range up to 33 V and supports PWM dimming control. It is housed in a 16-pin eTSSOP package (4.40 mm width) and is designed for automotive applications, holding AEC-Q100 qualification. The operating temperature range spans from -40°C to +125°C.

Feature Summary

• Automotive-grade reliability with AEC-Q100 certification
• Integrated boost topology for efficient LED driving
• Two-channel constant current source configuration
• Supports PWM dimming for brightness control

Applications

• Automotive exterior lighting systems
• Interior vehicle illumination
• LED backlighting modules

Procurement Notes

Verify the specific suffix ZLA3 against the manufacturer's latest datasheet to confirm pinout and packaging dimensions. Confirm AEC-Q100 compliance requirements for your target automotive application. Check for end-of-life or not-recommended-for-new-designations if sourcing for long-term production. Ensure ESD handling protocols are followed due to moisture sensitivity classification.

Selection Notes

Select this component when a dual-channel boost driver is required for automotive LED loads. Compare channel current capabilities against specific LED string requirements. Evaluate the eTSSOP-16 footprint against available PCB space. Consider thermal management needs given the 125°C maximum junction temperature rating and power dissipation characteristics under load.

Part Context

This part belongs to Lumissil's IS32BL series of LED lighting drivers. It complements other single or multi-channel variants in the portfolio, offering a balanced solution for applications requiring two independent LED channels. The series focuses on high-efficiency boost conversion and robust automotive environmental tolerance.

Replacement Considerations

Direct substitutes may include other 2-channel boost LED drivers with similar current ratings and eTSSOP-16 packages. Verify pin compatibility and electrical specifications before substitution. Cross-reference with Lumissil's internal family members for potential drop-in replacements with updated features.
