LV8702VGEVB

The LV8702VGEVB evaluation board from Texas Instruments is a product designed to allow users to efficiently prototype high voltage, low side gate drivers and power switches in various applications. This board helps to simplify the design process, allowing users to experiment with the PCB layout, component selection and the resulting performance of the complete system. In this article, we will cover the application field and working principle of the LV8702VGEVB.

Application Field

The LV8702VGEVB works in conjunction with other parts such as switches, diodes, and lower voltage gate drivers, to enable the user to rapidly prototype systems with lower overall component costs. The LV8702VGEVB has wide range of application due to its flexibility in controlling various power components. It can be used in customer’s product that require high voltage, such as SMPS, DC/DC and AC/DC converters, motor and motor controllers, Class-D audio amplifiers, welders, H-bridge and motor drives for robotics, and other industrial high voltage applications.

Operational Principle

The LV8702VGEVB is a device designed to control high voltage parts in a system. It uses a high voltage gate driver IC, the LV8700, to provide the interface between a low voltage microcontroller, microprocessor, or field programmable gate array (FPGA) and a high voltage power component. The LV8700 is an innovative, low-side, high-voltage gate driver, enclosed in small 5mm x 5mm QFN package. The device has been designed to enable easy implementation of designers’ requirements by allowing the control of a wide range of power components. It integrates three H-bridge drivers in a single package, with each H-bridge able to sink 1A (2A peak).

The LV8702VGEVB evaluation board uses the LV8700 to create a high voltage gate driver. The boards are designed with a single-ended, high voltage output and a logic output, allowing the user to easily evaluate the LV8700’s performance with a 6V to 36V input voltage. The LV8700 is used to drive an external switch in a switched-mode power supply (SMPS), a Class-D audio amplifier, a motor drive, or a welders. It supports low operating voltage, wide range of operating frequency, and wide operating temperature, suitable for variety of customer applications.
