Current Sensor
◆Instructions
of use
1. When the test current passes through the sensors you can get the size of the output voltage.
(Warning: wrong connection may lead to sensors damage)
2. Based on user needs, the sensors output range can be appropriately regulated.
3. According to user needs, different rated input currents and output voltages of the sensors can
be customized.
RESTRICTIONS ON PRODUCT USE
The information contained herein is subject to change without notice.
BYD Microelectronics Co., Ltd. (short for BME) exerts the greatest possible effort to ensure high quality and
reliability. Nevertheless, semiconductor devices in general can malfunction or fail due to their inherent
electrical sensitivity and vulnerability to physical stress. It is the responsibility of the buyer, when utilizing
BME products, to comply with the standards of safety in making a safe design for the entire system,
including redundancy, fire-prevention measures, and malfunction prevention, to prevent any accidents, fires,
or community damage that may ensue. In developing your designs, please ensure that BME products are used
within specified operating ranges as set forth in the most recent BME products specifications.
The BME products listed in this document are intended for usage in general electronics applications
(computer, personal equipment, office equipment, measuring equipment, industrial robotics, domestic
appliances, etc.). These BME products are neither intended nor warranted for usage in equipment that
requires extraordinarily high quality and/or reliability or a malfunction or failure of which may cause loss of
human life or bodily injury (“Unintended Usage”). Unintended Usage include atomic energy control
instruments, airplane or spaceship instruments, transportation instruments, traffic signal instruments,
combustion control instruments, medical instruments, all types of safety devices, etc.. Unintended Usage of
BME products listed in this document shall be made at the customer’s own risk.
