VAS5175数据手册Chip-Lead中文资料规格书

描述 Description

The VAS5175 is a 5V-24V input, highly integrated Li-ion/ Li-polymer battery switching charger IC with high accuracy charge current and voltage regulation. It closely monitors the battery pack temperature to allow charge progress only in a present temperature window. It also provides battery detection, pre-conditioning, charge termination, and charge status monitoring. The thermal regulation loop reduces charge current to maintain the junction temperature of 125°C during operation. If the junction temperature exceeds 155°C, it performs over-temperature shutdown and stops operating to ensure safety.

The VAS5175 is suitable for 1Cell / 2Cells battery charging. It integrates 24V rating, low Ron N-FET with a 1.0MHz synchronous buck for efficient battery charging and simply components and PCB design.

VAS5175 is available in SOP8-e package.Applications
