AP91351MN2-DT8-7

The AP91351MN2-DT8-7 is an integrated power switch chip from Anpec Electronics Corporation. The device is designed to provide a direct replacement for a wide range of application and work in various solution. It comes with a variety of features like high current rating, temperature protection, high performance current limited switching, soft start and a wide range of adaptive protection features.

AP91351MN2-DT8-7’s application field is mainly in power management solutions such as graphics cards or digital control conversion systems which require high-speed current limited switching. Due to its current rating, the chip also can be used in automotive subsystems such as EPS (electric power steering) systems, motor controllers, and light control systems. In addition, it could be used in high-end consumer electronics like TV, DVD players, and set-top boxes, as well as FPGAs, microcontrollers, and other embedded control solutions.

The working principle of the AP91351MN2-DT8-7 is based on the concept of Highside Nch FETs (Field Effect Transistors). It contains four independent N-channel FET footings, which are responsible for the current flow in and out of the device. When the FETs are turned on, current flows from the supply to the load. On the other hand, when the FETs are turned off, the current stops flowing and the device\'s current limit protection function is activated.

The AP91351MN2-DT8-7 also has an adjustable soft start function to protect the load when the device is initially powered. It enables the switch to gradually increase the current until it reaches its maximum current value. This prevents the device from drawing out large currents from the power source at once, thus reducing the risk of overloading the power source.

The AP91351MN2-DT8-7 integrates three temperature protection functions as well. These three-temperature protection functions include overtemperature protection (OTP), over-temperature warning (OTW) and thermal fault protection (TFP). The OTPaction triggers a power-off state above a preset upper temperature. The OTW action triggers an alert state at a slight lower temperature. The TFP action triggers a power-off state at a lower temperature.

The AP91351MN2-DT8-7 also comes with an adjustable current-limit protection feature. This feature ensures that the power switch will not exceed the preset current limit when the load is driven by an inductive component. By controlling the current, it prevents dangerous over-currents that may cause an over-voltage on the power supply or a short circuit in the system.

In conclusion, the AP91351MN2-DT8-7 is a highly-integrated integrated power switch chip with a wide range of features and functions. It can be used in multiple applications and is suitable for both consumer and automotive solutions. It offers high current ratings, temperature protection, adjustable soft start and current limit protection, and a wide range of other features. With its high performance and wide adaptability, it is an ideal solution for power management.
