About this document

Scope and purpose
The TLE4241GM is an AEC qualified adjustable current LITIX
embeds:
Built-in diagnosis and protection features
Adjustable constant output current up to 70 mA
Wide input voltage range
Voltage loop availability to implement constant output voltage power supply
The device also incorporates a PWM input that offers the possibility to adjust the LED brightness by pulse width
modulation.
The TLE4241SYS_SHIELD can be used for:
Standalone evaluation board for TLE4241GM device
Shield for Arduino
The board is especially suited to quickly setup demos in the context of blind spot indication as it features input
for ultrasound sensor, has an integrated buzzer and features 3 LEDs. Such designs are typically found in rear
radar applications or are directly integrated into mirrors.
Intended audience
The scope of this user guide is to provide instructions on the use of TLE4241SYS_SHIELD.
This user guide describes the TLE4241SYS_SHIELD with PCB version P02. Additionally, schematic version S02 is
described.
Evaluation board
This board is to be used during the design-in process for evaluation and proof of concepts for new projects
adopting the TLE4241GM.
Note:
PCB and auxiliary circuits are NOT optimized for final customer design.
