Gate drivers are an important and indispensable part of PMIC(Power Management Integrated Circuit). They are used to control the switching of power transistors, such as MOSFETS, by driving the gate of the transistor. The TSC428EPA Gate Driver is designed to provide high-speed and efficient switching of power transistors and drives the gates of large MOSFETS, enabling fast transistor switching and power conversion.

Application Field

The TSC428EPA is ideal for applications such as industrial motor drives, DC-DC converters and lighting control systems. It offers an integrated current limit protection, making it ideal for applications with high switching requirements. The TSC428EPA can be used in both single-phase and multi-phase switching applications, allowing for low-speed operation and the ability to directly drive large power MOSFETS from supply voltages up to 80V.

Working Principle

The TSC428EPA consists of low-side and high-side drivers. The low-side driver consists of a high-current output transistor and circuit protection, while the high-side driver consists of a high current P-channel MOSFET, a power supply voltage regulator, a current limit sensing circuit, and a voltage regulator circuit. When the low-side driver is enabled, the current limit sensing transistor will detect an over-current condition and will trigger the protection circuitry, due to its high capacity, it will be able to handle over-duty cycles. The voltage regulator built into the high-side driver will ensure that the gate voltage remains constant regardless of supply voltage, making sure the MOSFET remains in the active region. In addition, the TSC428EPA offers the ability to operate on gate drive voltages up to 15V, and is designed to provide short-circuit protection and fast switching performance.

Conclusion

The TSC428EPA Gate Driver is designed to provide fast, efficient switching of power transistors, and it is well-suited for various applications, such as industrial motor drives, DC-DC converters, and lighting control systems, thanks to its integrated current limit protection and the ability to directly drive large power MOSFETS from supply voltages up to 80V. Furthermore, the TSC428EPA offers the ability to operate on gate drive voltages up to 15V, as well as short-circuit protection and fast switching performance.
