Constant Current Driver IC Chip for Automobile Electronic Circuits

Product Overview

Our automotive-grade constant current driver IC chips are purpose-engineered for reliable LED lighting and power management in modern vehicle electronic systems. Designed to meet strict automotive industry requirements, these highly integrated ICs minimize external component count, reduce BOM costs, and deliver exceptional efficiency and current accuracy for all types of automotive LED applications.

With built-in power MOSFETs, advanced protection features, and flexible dimming capabilities, these driver ICs provide a compact, optimized solution for both traditional and intelligent automotive lighting systems, from entry-level to high-end adaptive headlamp applications.

Key Features

  • Wide input voltage range (5.5V–100V) compatible with 12V, 24V, 48V and 72V automotive and industrial power systems

  • High integration with built-in power MOSFETs (60V–100V rating) eliminating the need for external MOS components

  • High conversion efficiency up to 96% with low on-resistance for minimal power loss and heat generation

  • High-precision constant current output with accuracy up to ±3%, ensuring uniform LED brightness

  • Flexible dimming options: supports analog dimming, PWM dimming, and brightness mode switching (full/low brightness)

  • Supports output currents from 100mA up to 2.5A, adaptable to low, medium and high-power LED loads

  • Patented control architecture eliminates need for external loop compensation, simplifying PCB design

  • Comprehensive built-in protection: under-voltage lockout, over-temperature protection with gradual current reduction, output short-circuit protection, and LED open/short-circuit detection

  • Optimized EMI performance with spread-spectrum modulation and frequency jitter to reduce electromagnetic interference

  • AEC-Q100 qualified for automotive applications, operating across a wide junction temperature range of -40°C to 150°C
