BTS5590G – Rear Lamp Lighting Power Driver IC for Automotive Taillight Systems, Quad High-Side Switch

The BTS5590G is a dedicated power driver IC designed for automotive rear lamp lighting systems.
It integrates four independent high-side channels for controlling taillights, stop lamps, turn signals, and reverse lights.
This chip is a common wear-and-tear part for tail light modules due to its reliable protection features.

Each channel supports continuous current up to 3A with built-in overcurrent and overtemperature shutdown.
The device includes open-load detection and short-circuit protection for both supply and ground faults.
It operates directly from 12V automotive battery systems with load dump immunity up to 40V.

Advanced diagnostic feedback is available through a dedicated status pin for each channel.
The BTS5590G supports PWM dimming control for daytime running lights and dynamic turn signals.
It features very low standby current to minimize battery drain when the vehicle is off.

This power driver simplifies PCB design by integrating four power switches in a single package.
It is optimized for rear combination lamps, central high-mounted stop lights, and trailer lighting modules.
Operating temperature range covers -40°C to +150°C for reliable performance in harsh under-vehicle environments.

Use the BTS5590G for automotive aftermarket taillight repairs or replacement of burned driver ICs.
It improves system reliability and reduces repair time compared to discrete transistor solutions.
