Operating Principle of LTC1693-3CMS8#PBF

The LTC1693-3CMS8#PBF gate driver works on the principle of an external power transistor. The device features two inputs, the Gate and the Enable signals, that can be used to control the power transistor’s on/off switching. The Gate signal is responsible for actively switching the power transistor while the Enable signal is used as an enable/disable signal that will turn on or off the power transistor. The device also features a Current Limit control pin that can be used to control the maximum current that is allowed to flow through the power transistor. The device features an adjustable dead-time generator that can be used to set the maximum allowable dead time for the switching of the power transistor. This can be used to regulate the flow of the current and to protect the power transistor from damage due to over-current. Furthermore, the device includes a thermal protection circuit that will shut down the device if the temperature exceeds a certain threshold.

Application Fields

The LTC1693-3CMS8#PBF is a versatile and reliable gate driver for power-intensive applications. It can be used as a PMIC in a range of applications such as portable medical devices, displays, lighting systems and industrial control systems.
