Advantages of SPDU:

Fail-safe Mode: The unique Fail-safe Mode of Senpeng SPDU ensures that in the event of a severe system failure, the software and hardware watchdogs force a system reset. During this time, the Limhome Mode takes control of critical load outputs, ensuring that important functions are maintained and preventing the failure of essential system functions.
Maintenance-free lifespan: SPDU design enables the module to operate without maintenance for the entire lifespan of the vehicle (chip switches with more than 10^15 cycles without performance degradation).
Safety goals: The device does not open or close unexpectedly, and it remains undamaged in application due to load issues.
Enables intelligent connectivity between cloud-based backend and client applications for data exchange.
Supports functional safety designs compliant with national standards.
Supports low-power designs for applications with virtual power master switches.
