IS32LT3180-ZLA3-TR

Overview

The IS32LT3180-ZLA3-TR is a dual-intensity linear current driver designed for automotive applications. It operates within an input voltage range of 5 V to 28 V and features two independent output channels. The device supports PWM dimming control and includes integrated MOSFETs for efficient current regulation. It is housed in an eTSSOP-16 package (5.0 mm x 6.4 mm) and is rated for operation between -40°C and +125°C. This component is specifically engineered for driving resistive-capacitive loads (RCL) such as daytime running lights.

Feature Summary

• Dual-channel linear current driver architecture for independent intensity control
• Integrated MOSFETs enable direct drive capability for resistive-capacitive loads
• Supports pulse-width modulation (PWM) dimming for brightness adjustment
• Designed with dynamic headroom control for optimized power efficiency

Applications

• Automotive daytime running light (DRL) systems
