BD00IA5MEFJ-M
針對車用裝置的0.5A可變輸出／固定輸出LDO穩壓器
BDxxIA5MEFJ-M系列是可提供0.5A輸出電流的穩壓器。輸出精度為±1%。有可使用外接電阻在0.8V～4.5V範圍內任意設置輸出電壓的可變型以及1.0V/1.2V/1.5V/1.8V/2.5V/3.0V/3.3V固定輸出型兩種。封裝組件採用散熱性優良的HTSOP-J8。本機型內建用於防止因輸出短路等發生IC破壞的過電流保護電路、關斷時使電路電流為0µA的ON/OFF開關、以及防止因過負載狀態等使IC發生熱破壞的溫度保護電路。另外，採用了陶瓷電容，有助於整機的小型化和長壽化。

- CISPR25 Class5 compliant 8 rails power tree Reference Design for Automotive ADAS/Infotainment application
This reference design is a power tree solution board developed for infotainment devices such as automotive clusters and center information displays and for ECUs for ADAS application. The power system that can support functional safety is integrated on a single board to achieve the optimal configuration as a power tree. Excellent EMC performance that meets CISPR25 Class 5 even at all power supply rails are enabled, and reduces heat generation of each device by distributing high-efficiency DCDCs. In addition, two supervisor ICs with self-diagnosis functions can monitor the output of all power rails and contribute to a higher level of functional safety.
- Automotive Infotainment/ADAS 8-channels power tree reference design
- Verified to satisfy EMC CISPR 25 class 5 standard without common mode filter
- In order to avoid the AM radio frequency bands All DC/DC converters operate at a switching frequency of 2.2 MHz or higher.
- Thermal characteristics tested
- voltage monitoring for 8-channel power tree to improve the functional safety ASIL level
- Space saving by integrating multiple power trees
