Evaluation and Demonstration Boards and Kits are used to evaluate and demonstrate the physical characteristics and performance of a device. The TPS22981EVM from Texas Instruments is an evaluation and demonstration board that is used to evaluate the performance of its TPS22981 high-speed gate-drive IC. The board has been designed to help designers quickly and easily evaluate and demonstrate the features and functions of the TPS22981.

The TPS22981EVM is a two channel gate driver board designed for driving high power, high voltage power MOSFETs. The board has on-board high and low side FETs, a DC-DC converter, power-on reset circuitry, and two isolated gate drivers. In addition, the board features an external adjustable gate drive voltage, a voltage measurement point to measure the gate voltage, and a VCC under voltage lockout function. The board also has a built-in LED power indicator, a controllable diode for testing, and a DC power connector for powering the board from a DC power supply.

The TPS22981EVM is designed to work with a wide variety of MOSFETs. It has two channels of independent gate drive capability and supports a wide range of MOSFETs on either channel as well as a variety of control inputs. The board features a 3.3V logic range and can operate up to 20A peak at up to 30V voltage. The board is also capable of driving more than one MOSFET at a time and capable of supplying the MOSFETs with pulse and forget loading without having to be reset.

The TPS22981EVM uses a programmable gate drive voltage to provide the MOSFETs with the optimal voltage level for their particular application. The adjustable voltage range can be set to any value between 0V and 30V. This feature allows the user to adjust the gate voltage to match the specific MOSFETs used on the board and ensure that the maximum performance is achieved. Additionally, the board includes an overvoltage protection circuit so that the gate drive voltage is limited to a safe value if the voltage exceeds the set voltage.

The board also includes a power-on reset circuit which will reset the board when power is first applied. This feature helps ensure that the board will not have any unexpected behavior when power is first applied. The board also includes a VCC under voltage lockout circuit which will shut off the gate driver if the VCC voltage drops below a certain level. This prevents the board from being damaged due to a low power supply voltage.

The TPS22981EVM application field and working principle are designed to evaluate and demonstrate the performance and features of the Texas Instruments\' TPS22981 high-speed gate drive IC. The board has been designed to provide an easy and efficient way to evaluate and demonstrate the features and functions of the IC. It includes an adjustable gate drive voltage so the user can adjust the voltage to match the specific MOSFETs used on the board. The board also includes power-on reset circuitry, and a VCC under voltage lockout function to protect it from damage due to a low voltage condition.
