Application field

The X40410S8I-B is an ideal solution for a variety of current and voltage supervisor applications. For example, it can be used as a low voltage warning supervisor in portable and mobile devices, ensuring the system is operating correctly and setting a basic warning threshold levels. It can also be used as a fail-safe voltage regulator in cases where high voltage spikes or overloads occur. In addition, the X40410S8I-B also provides an integrated temperature sensor for thermal limiting of the system.

For larger, more complex multi-processor systems, the X40410S8I-B can provide a comprehensive monitoring solution. It can detect various system parameter levels and set one or more thresholds. For instance, it can detect current and voltage levels, temperature and input voltage levels. By setting specific thresholds, the X40410S8I-B can alert the control system when one of these parameters exceeds recommended levels to ensure optimal operation and protect the system from damage.

The X40410S8I-B is also well suited to automotive applications. It can provide an efficient and reliable way to monitor the power supply to ensure it is operating within the required range and provide measures to protect the system from over-temperature damage. It can also be used to monitor the temperature of the vehicles engine and activate temperature alarms in certain conditions.

Working principle

The X40410S8I-B is designed to provide a robust supervisor solution for a variety of applications. It consists of a P-Channel MOSFET that is used to detect the presence of a voltage, usually from an external power source. Initially, the MOSFET is in an OFF state, but when an adequate voltage is detected, the MOSFET shuts the circuit and enables the voltage to be measured. The X40410S8I-B can be programmed to trigger an alarm when an input voltage exceeds a certain pre-defined level, generally by means of a positive or negative temperature coefficient.

The X40410S8I-B also provides two integrated diodes to protect the system against high voltage transients. These diodes act as voltage clamping diodes and are activated when a high voltage spike is detected. The diodes allow the system to remain functional without being unnecessarily exposed to high voltage transients.

The X40410S8I-B also provides an integrated temperature sensor. This temperature sensor can be used to provide thermal limiting for the system, setting temperature thresholds for the system to alarm in case of high temperature operation. This can help prevent system damage due to excessive heating.

Conclusion

The X40410S8I-B is a robust and versatile P-Channel MOSFET Supervisor that is suitable for a variety of applications. It is capable of detecting the presence of a voltage, setting warning thresholds and providing integrated diodes and temperature sensors for protection against voltage transients and overheating. It is an ideal choice for portable and mobile devices, multi-processor systems, automotive applications and numerous other current and voltage supervisor applications.
