About this document
Scope and purpose
The scope of this user manual is to provide instructions on the use of the TLD7002-16SYS_EVAL board.
The TLD7002-16SYS_EVAL is an evaluation platform for the TLD7002-16ES LED driver, which features:
•
16 independent channels set from 5 mA to 76.5 mA
•
Power stages can be paralleled for higher currents
•
16 independent 14 bits PWM engines
•
UART over CAN interface (HSLI High speed lighting interface)
•
OTP (one time programmable) configuration memory
Intended audience
Hardware and Firmware engineers
Evaluation board
This board is to be used during the design-in process for evaluating and measuring characteristic curves, and
for checking datasheet specifications.
Note:
PCB and auxiliary circuits are NOT optimized for final customer design.

Page 7: Quick Start
TLD7002-16SYS_EVAL board User guide 2 Quick start Quick start Operational modes summary The TLD7002-16SYS_EVAL can operate in three different manners. • Fail safe operation • GPINx direct drive control • HSLI bus control Fail safe operation The TLD7002-16ES devices on the TLD7002-16SYS_EVAL are programmed watchdog timeout set to 2 s. If within 2 seconds from the board power up, no HSLI communication is received by the TLD7002-16ES, then the fail safe configuration will turn on as shown in figure below. -
