It protects this part from lightning surge and static electricity. Precautions on use of products This product has built-in over current (reset type) and over voltage (latch type) protection function to prevent destruction at abrupt error. These protection functions are effective for prevention against destruction owing to abrupt accident, therefore, avoid using them for continuous protection circuit operating, or at transition Output Current Io (mA) Appendix Notes No technical content pages of this document may be reproduced in any form or transmitted by any means without prior permission of ROHM CO.,LTD.
