These include high-current and high-voltage automotive control and display systems, which need extensive circuitry to manage power requirements and enable flexibility in applications such as door locks, airbags, and other safety features. The S-8355K31MC-NAQT2G is also suitable for motors, induction heating systems, and medical applications, such as home care devices, patient monitoring systems, and implantable medical devices. The high power rating and advanced protection features make the S-8355K31MC-NAQT2G an ideal choice for use in high-power applications.

Working Principle

The S-8355K31MC-NAQT2G is a switch-mode DC/DC controller that uses pulse-width modulation (PWM) control to regulate the output voltage. The output voltage is determined by the switching duty cycle of the power MOSFETs. The PWM controller continually monitors the output voltage and adjusts the switching duty cycle accordingly, thus providing stable voltage regulation. The S-8355K31MC-NAQT2G also features a cycle-by-cycle current protection circuit that shuts down the MOSFETs when the current sense limit is exceeded. This allows the S-8355K31MC-NAQT2G to protect itself and the system from overcurrent conditions.

In addition, the S-8355K31MC-NAQT2G features an adjustable over-voltage protection (OVP) circuit that monitors the output voltage and shuts down the MOSFETs when the over-voltage limit is exceeded. This ensures that the output voltage remains within the specified range and prevents system damage from over-voltage conditions. The S-8355K31MC-NAQT2G also features an adjustable under-voltage protection (UVP) circuit that monitors the output voltage and shuts down the MOSFETs when the under-voltage limit is exceeded. This ensures that the output voltage remains within the specified range and prevents system damage from under-voltage conditions.

The S-8355K31MC-NAQT2G is also equipped with an output-short-protection (OSP) circuit that shuts down the MOSFETs when a short circuit condition is detected. This prevents damage to the controller and helps to ensure a safe and reliable power source for the application. Additionally, the S-8355K31MC-NAQT2G provides built-in fault logging capabilities that allow for a better understanding of the root cause of any issues that may arise.

In summary, the S-8355K31MC-NAQT2G is a high-performance switching-mode DC/DC controller that is ideal for use in high-power applications. The S-8355K31MC-NAQT2G offers a wide range of output voltage options, along with advanced protection features such as over-voltage, under-voltage, and output-short-protection, which help to provide a safe and reliable power source for the application. The S-8355K31MC-NAQT2G is specifically designed to meet the stringent voltage requirements of the automotive, industrial, and medical industries.
