PolySwitch® Series, Power Distribution Switches, Load Drivers

The products in this category are solid-state devices that serve as switches, allowing the flow of current to be connected or interrupted to a supported load. They are controlled by a logic-level control signal that is incapable or unsuitable for directly supplying the load. These devices integrate a semiconductor switching device and incorporate additional functions such as over-voltage clamping, current limiting, and under-voltage lockouts, which differentiate them from other IC and discrete components. The semiconductor switching device used in these products allows for the efficient transfer of power to the load while minimizing power loss. Additionally, the integrated supporting components and functions enable these devices to provide superior protection against electrical anomalies, ensuring that the load is supplied with stable and reliable power. The over-voltage clamping feature protects against voltage spikes that can cause damage to the load and other components in the circuit. The current limiting function protects against excessive current flow, which can lead to overheating and component failure. The under-voltage lockout feature ensures that the load is not supplied with insufficient power, preventing damage and instability. Overall, these solid-state devices offer a high level of control and protection for electrical systems. Their integration of semiconductor switching devices and additional supporting components/functions enables efficient power transfer and protection against electrical anomalies, making them essential components in many different applications.
