＜High Voltage Safety Precautions＞
◇ Read all safety precautions before use
Please note that this document covers only the BD18353EFV-M evaluation board
and its functions. For additional information, please refer to the datasheet.
To ensure safe operation, please carefully read all precautions before
handling the evaluation board
Depending on the configuration of the board and voltages used,
Potentially lethal voltages may be generated.
Therefore, please make sure to read and observe all safety precautions
described in the red box below.
Before Use
-
Verify that the parts/components are not damaged or missing (i.e. due to the drops).
-
Check that there are no conductive foreign objects on the board.
-
Be careful when performing soldering on the module and/or evaluation board to ensure that solder splash does not occur.
-
Check that there is no condensation or water droplets on the circuit board.
During Use -
Be careful to not allow conductive objects to come into contact with the board.
-
Brief accidental contact or even bringing your hand close to the board may result in discharge and lead to severe injury or death.
Therefore, DO NOT touch the board with your bare hands or bring them too close to the board.
In addition, as mentioned above please exercise extreme caution when using conductive tools such as tweezers and screwdrivers. -
If used under conditions beyond its rated voltage, it may cause defects such as short-circuit or, depending on the circumstances, explosion or other permanent damages.
-
Be sure to wear insulated gloves when handling is required during operation.
After Use -
The ROHM Evaluation Board contains the circuits which store the high voltage. Since it stores the charges even after the connected power circuits are cut, please discharge the electricity after using it, and please deal with it after confirming such electric discharge.
-
Protect against electric shocks by wearing insulated gloves when handling.
This evaluation board is intended for use only in research and development
facilities and should by handled only by qualified personnel familiar with all
safety and operating procedures.
We recommend carrying out operation in a safe environment that includes the
use of high voltage signage at all entrances, safety interlocks, and
protective glasses.
Introduction
This user’s guide will provide the necessary steps to operate the Evaluation
Board of ROHM’s BD18353EFV-M LED Driver.
This document includes the external parts, operating procedures and
application data.
Description
This Evaluation Board was developed for ROHM’s LED Driver BD18353EFV-M.
BD18353EFV-M is a 1ch LED Controller.
High side current detection amplifier is built-in. PWM dimming duty can be
freely set with built-in PWM generation circuit.
PWM dimming realizes by driving an external P-ch MOSFET. Outputs abnormal LED
status to the FAULT_B pin. Two systems of analog dimming are built-in. High
precision 3.0V output power supply for analog dimming and PWM dimming setting
is built-in.
Application
Automotive Exterior Lamps (Rear, Turn, DRL/Position, Fog, High/Low Beam etc.)
