LP877451Q1EVM: Please check the hardware ASIL rating of the LP877451A1RXVRQ1 product.

Hi Do-hyun,

Do you have access to the functional safety documentation for the device? This is available here under NDA: https://www.ti.com/drr/opn/LP8774X-Q1DOCUMENTS Submit the request if you do not already have access. 

From the Safety Manual for this device, Appendix A: 

"A.1 How the Functional Safety Lifecycle Applies to TI Functional Safety Products
TI has tailored the functional safety lifecycles of ISO 26262 and IEC 61508 to best match the needs of a functional Safety Element out of Context (SEooC) development. The functional safety standards are written in the context of the functional safety systems, which means that some requirements only apply at the system level. Since TI functional safety components are hardware or software components, TI has tailored the functional safety activities to create new product development processes for hardware and for software that makes sure state-of-the-art techniques and measures are applied as appropriate. These new product development processes have been certified by third-party functional safety experts. To find these certifications, go to TI.com/functionalsafety."

The datasheet has listed this as "functional safety-compliant device". That classification is defined at the ti.com/functionalsafety website. There is also a list there of the documentation we provide for functional safety-compliant devices to help you as the system integrator to help you achieve the system level ASIL requirement. 

Regards,

Katie
