The TPS28225DRBRG4 is a versatile, low-side gate driver that is used in many power management applications. It is part of Texas Instruments’ power management portfolio, which is designed to simplify powertrain design and reduce board space.

The TPS28225DRBRG4 is most commonly used as a low side gate driver for high current switching. It is designed to achieve very low dead time and high frequency operation, providing the necessary flexibility for high speed automotive, lighting and industrial motor applications. Furthermore, the gate driver can be used to drive logic-level, high-side and low-side switch power devices, making it suitable for a wide range of applications.

The TPS28225DRBRG4 features an integrated regulator and sense resistor to provide a current sense reference voltage. Three extra pins allow control of the VCCP output, which is used to regulate the power supplied to the outputs of the device. This ensures that the device operates within the limits of the device and ensures safe operation. The device provides an integrated soft start feature, with adjustable soft start time, allowing for improved in-rush current limiting.

The TPS28225DRBRG4 is designed with a low operating voltage of 5V making it suitable for automotive and industrial applications. The device is operated by a 5V/3V or a 3V/1.8V logic level that is compatible with any standard controller or processor. The device can be used for single-ended or differential outputs. It also supports a wide input voltage range from +3V to +12V, allowing for an even wider range of applications.

The TPS28225DRBRG4 is a low-side gate driver that is optimized to drive MOSFETs, IGBTs, as well as other power switches with fast turn-on and turn-off times. It provides a high-speed, high current drive capability and low dead time construction, with adjustable dead time compensation. These features make the device suitable for high speed switching, motor control and lighting applications that require greater current capability and power efficiency.

The TPS28225DRBRG4 works by providing a full-bridge control to switch the polarity of the MOSFET or IGBT as required. The device is enabled by an enable signal sent from the gate driver circuit or controller. This signal causes the power switch to be enabled to a high level, allowing for the current to flow through the circuit. Once the enable signal is removed, the power switch is turned off and the current path is removed. The device also has a safety feature that enables automatic power-off if the enable signal is removed for an extended period of time.

The TPS28225DRBRG4 is designed to be used in many automotive, lighting and industrial motor applications. It is an ideal choice for applications that require efficient and reliable low side gate driving. The device features an integrated regulator, low operating voltage and adjustable dead time capability, making it an excellent choice for power management and switching applications.
