The product is SAE J1113 and SAE J1242 compliant and meets the requirements and standards of Q100.

Application Field and Working Principle

LTC4440EMS8E#PBF is primarly designed for automotive applications, offering a variety of features to ensure safety, including current foldback and overvoltage protection, power-on reset and brown-out, reverse current protection, and more. The power management works on a principle of detection and control. When power is applied, current through the external power MOSFETs is monitored. If current reaches the device\'s current setting, a signal is sent to the internal controller to reduce the voltage of the external FETs. This results in a lower power delivery and lowers power dissipated, limiting heat dissipation and extending the life of the system. The LTC4440EMS8E#PBF also provides a power-on reset and brown-out feature. This feature helps to ensure that the system functions only when powered properly. It also allows for improvements to system reliability, by ensuring that the system does not operate when the voltage drops below a certain level. Finally, the device also offers reverse current protection, which helps to prevent the power MOSFETs from suffering excessive damage due to a sudden change in current. Reverse current protection ensures that power is not supplied to the system at a rate that exceeds the current rating of the traces on the board or of the device.

Conclusion

LTC4440EMS8E#PBF is a powerful PMIC - Gate Drivers that offer a variety of features to ensure safety and reliability in a wide range of automotive applications. It features an integrated power controller, current foldback and protection features, power-on reset and brown-out, overvoltage protection, and reverse current protection. These features make the device ideally suited for use in applications such as PMICs, RKE systems, home automation systems, display power supplies, automotive electronics and more.
