RT9624BZS Working Principle

The RT9624BZS PMIC - Gate Driver IC has a number of features which make it suitable for applications involving clocking and resetting of the gate drivers. The working principle of the IC is quite simple. The IC has two inputs, one for the clocking signal (CLK) and the other for the reset signal (RST). It also has two output pins, one for the high side driver (HSD) and one for the low side driver (LSD).

When the CLK input is low, the gate driver IC provides an open-drain signal to the gate of the MOSFET or IGBT which acts as a high side driver. When the CLK input is high, the signal provided to the gate of the MOSFET or IGBT is a logic high signal, which then switches the MOSFET/IGBT on. Similarly, when the RST input is low, the RT9624BZS PMIC - Gate Driver IC provides an open-drain signal to the gate of the MOSFET/IGBT which acts as a low side driver. When the RST input is high, the signal provided to the gate of the MOSFET/IGBT is a logic low signal, which then switches the MOSFET/IGBT off.

The output current ratings of the RT9624BZS PMIC - Gate Driver IC can be adjusted to suit the requirements of the application by selecting one of the three/six drive current levels. Additionally, the IC also offers protection against over-voltage and over-current by providing short-circuit protection and a built-in thermal shutdown function.

Conclusion

In conclusion, the RT9624BZS PMIC - Gate Driver IC is a powerful IC suitable for a variety of automotive, industrial, and consumer applications. Its features make it ideal for applications requiring clocking and resetting of the gate drivers, with an operating temperature range of -40˚C to 125˚C and output current ratings up to 3A. The IC also provides protection against over-voltage and over-current by providing short-circuit protection and a built-in thermal shutdown function.
