PMIC - Power Distribution Switches, Load Drivers are used in many applications as they are able to supply and/or restrict the current/voltage levels through different types of electronic system. One example of such a device is the ITS436L2SHKSA1. The ITS436L2SHKSA1 Power Distribution Switch is a 3-channel MOSFET based load driver that can provide up to 1-A per channel. It is mainly used in the fields of power supplies, automotive, test, and measurement applications.

The ITS436L2SHKSA1 is an integrated switch, combining both a high-side and a low-side output with an integrated gate driver and protection circuit. This combination provides isolation, standardization of the protection architecture, and improved performance as compared to discrete solutions. The integrated gate driver, in particular, helps eliminate the need for any additional on-board components, thereby improving system reliability. The gate driver contains various features such as short-to-battery protection, short-to-ground protection, and over-current protection.

The ITS436L2SHKSA1 is a monolithic device which also eliminates undesirable signal capacitance and parasitic effects. This allows for fast switching, low ripple, up to 1-A of continuous current per channel, and operation at up to 10 MHz of signal frequency. In addition, its low power consumption, low standby current, and low channel on-resistance further improve the overall system efficiency.

The basic working principle of the ITS436L2SHKSA1 is to receive a control signal and then to isolate the power and ground through a MOSFET-based switch, providing protection for the current and voltage levels in the system. It requires a high-voltage signal for control and when the voltage of this control signal rises above a certain predefined level, the ITS436L2SHKSA1 will enable or disable the switch. Additionally, it has various over-current protection and short circuit protection as well as low-side protection.

In summary, the ITS436L2SHKSA1 is an integrated switch that provides isolation, voltage, and current control. It has 1-A continuous current per channel, and its low standby power, fast switching, and low channel on-resistance make it well suited for many application fields ranging from power supplies and automotive to test and measurement applications.
