What is the HV9901NG-G Application Field and Working Principle?

The HV9901NG-G is an integrated high voltage gate driver circuit with an integrated boost converter. It is typically used to control switching or mid-high voltage (MOSFET) devices and it is based on the latest technology available from ON Semiconductor.

As a gate driver, the HV9901NG-G circuit offers a good amount of automated control. It is well-suited for applications in the automotive, industrial, and consumer markets. The HV9901NG-G can be used for switching devices such as STIs, IGBTs, MOSFETs, transistors, and TRIACs.

The HV9901NG-G circuit is designed with a low-voltage input and output (VSS, Vin, and Vout) and an integrated boost converter. This allows the circuit to use a full range of input voltages and thus provides greater design flexibility. The circuit is also capable of providing high-current drive outputs, which allows for reliable operation with large high voltage MOSFETs or transistors.

HV9901NG-G Working Principle

The working principle of the HV9901NG-G is similar to other high voltage gate drivers. The circuit starts by taking a low-voltage input. This input is then fed through the integrated boost converter, which increases the voltage to the output voltages necessary for driving the targeted device. Once the voltage is increased, the circuit then proceeds to amplify the signal, which allows the MOSFET or transistor to switch on or off.

The HV9901NG-G also provides a number of other features, including under-voltage protection and adjustable slew rate. Under-voltage protection prevents incorrect turn-on/off operations and can also prevent potential electrical damage. The adjustable slew rate allows for a smooth transition between the on and off states, which leads to quieter and vibration-free operations.

Conclusion

The HV9901NG-G is a sophisticated gate driver circuit which is well-suited for high-power switching or mid-high voltage devices. The circuit is quite versatile, supporting a wide range of input voltages, and it is equipped with a number of additional features such as under-voltage protection and adjustable slew rate.
