A gate driver is an isolated and high-powered interface between a low-current control signal and a high-current load. It is used to on/off power supply controlling devices in power conversion and motor drive systems. Gate drivers can deliver high power and switching speed, while isolating and protecting the control logic from these high power circuits. They are typically used in power converters and motor control applications. The Texas Instruments TPS2816DBVRG4 is a single-channel gate driver designed for driving large, high-side power MOSFETs or IGBTs. It is a universal gate driver that can be used for a variety of applications, including solar inverters, UPS, and switched-mode power supplies.

Functionality

The TPS2816DBVRG4 is a three-border gate driver designed specifically to drive large, high-side power MOSFETs or IGBTs. It is a single-channel device with a low-side drive option and a low output resistance. The low-side drive feature enables additional control flexibility, while the low output resistance helps ensure clean switching and minimal losses. The device also includes short circuit protection and current limit protection, providing protection in the event of an external fault.

Application Field

The TPS2816DBVRG4 is a versatile, high-performance gate driver that can be used in a variety of applications, including solar inverters, UPS, and switched-mode power supplies. The single-channel gate driver makes it ideal for applications where power MOSFETs or IGBTs need to be driven with a low-side drive option for improved flexibility. Furthermore, the wide range of protection features make it suitable for use in high-performance and high-reliability systems.

Working Principle

The TPS2816DBVRG4 is designed to drive large, high-side power MOSFETs or IGBTs, with a single-channel interface and a low-side drive option. It features a low output resistance, which helps ensure clean switching and minimal losses. It also includes short-circuit protection and current limiting protection to prevent damage caused by external faults. In order to operate correctly, the device requires an external control signal to control the gate drive signal, as well as an external power supply to supply the necessary power.

When the control signal is activated, the device switches on, providing the necessary drive signal to the power MOSFETs or IGBTs. The drive signal is then amplified and buffered, before it is applied to the gate of the device’s output device. When the control signal is deactivated, the device switches off, discharging the gate drive signal and shutting off the output device.
