Working Principle

The S-1000N35-I4T1U utilizes a combination of voltage monitoring and voltage switching technologies to provide safe, reliable power monitoring and management. The voltage monitoring function is used to measure the voltage of connected rails, which is then compared to the setpoints stored in the internal ROM. If the monitored voltage is above the setpoint, it is switched off, otherwise it is switched on. The voltage switching circuit then switches on/off the connected rails depending on the measured/stored voltage levels. Additionally, the component can provide fixed time delays and voltage sequencing, allowing the connected rails to turn on in a predefined order. This ensures a smooth startup process with proper input voltage sequencing.

To protect against power surges, the S-1000N35-I4T1U also implements a reverse-battery protection circuit that limits the power that can flow in the opposite direction. This is an important safety feature to ensure system stability, especially in vehicles and other environments that experience large power fluctuations. Additionally, the component also supports overtemperature protection and UVLO (Under-Voltage Lock-Out) features, further increasing the overall system’s safety.
