PMIC – Gate Drivers are important electrical components used to control and manage the high-power present in petrochemical and industrial automation applications. The TPS2813DRG4 is a particularly advanced device in this category, and is used for a variety of purposes, including controlling high-voltage switching circuits and providing protection against transient voltage spikes. Its features and capabilities will be reviewed in the following sections.

Application Fields

The TPS2813DRG4 is an ideal device to use for the control of high-power switching circuits, as it offers superior protection with its integrated features. Its wide input voltage range of 4.5V to 100V also makes it suitable for a range of applications, including automotive, industrial and communications systems. Its control capability is further emphasized by its three-state output level control, which allows precise modulation of the power being outputted.

The device also provides an integrated timer, which can be set to enable or disable the output for a given period of time. This feature is useful for applications that require an adjustable performance level, such as motor control systems.

Finally, its high-voltage protection capability makes it an ideal choice for use in high-power switching systems that are prone to transient events. With its built-in Over-Voltage and Under-Voltage protection, the device can protect against potentially damaging surges up to 600V.

Working Principle

The TPS2813DRG4 is based on a monolithic integrated circuit design, and utilizes a MOSFET gate driver integrated inside a single package. This type of design reduces the board space needed, while still providing maximum protection.

At its core, the device functions by connecting the high voltage rail to the gate of the MOSFET by means of the driver. This design allows for optimal switching and protection, as the gate driver is held at a low voltage. This ensures that the gate-source voltage difference is kept to a minimum, reducing power losses and increasing operational efficiency.

In addition, the device incorporates an integrated timer that can be used to precisely control the flow of current. When enabled, this feature can be used to limit the flow of power being outputted, adjusting the duration that the output is active. This feature is beneficial if the output needs to be controlled in order to avoid exceeding the device’s maximum current rating.

Finally, the device also includes built-in Over-Voltage and Under-Voltage protection, which allow for the switching of power up to 600V. This ensures that the device is resilient in transient voltage events, providing an extra level of protection to the circuit.

In conclusion, the TPS2813DRG4 is an advanced and powerful Gate Driver designed for use in high-power switching applications. Its wide input voltage range, integrated timer and protection capabilities make it an ideal choice for a variety of applications.
