L9680中文资料用于中/高端应用的高级安全气囊IC数据手册ST规格书

描述 Description

The user can select both ECU logic voltage (VCC at 3.3 V or 5.0 V) and energy reserve output voltage (at either 23 V or 33 V). Deployment voltage is set to a maximum of 25 V for all profiles and can be controlled through external safing switch circuit using the high side safing switch reference enabled through the system SPI interface or the arming logic.
