PMIC - Gate drivers are an important part of power management integrated circuits (PMICs), and RT7021BGS is one of its products. It provides a versatile package in sophisticated gate drivingcircuits, which have been essential in creating low power, energy efficient electric circuits.

RT7021BGS contains six high-side switches, three low-side switches, and a bootstrap capability. Each high-side switch is capable of driving external power MOSFETs and/or IGBTs up to 2A. The low-side switches are responsible for switching the bootstrap capacitors or other auxiliary devices.

The working principle of RT7021BGS is based on the concept of "driver protection" that is used to guard against short-circuits and over-currents by regulating the gate currents so that the maximum predetermined limit is not exceeded. It does this by limiting the maximum high-side switch current to 2A, and the maximum low-side switch current to half of that value. This ensures that the device will not become damaged due to excessive current.

RT7021BGS has been designed to meet a variety of applications such as switched-mode power supplies (SMPS) and motor control applications. Its switching speed is capable of handling loads at frequencies up to 10MHz, making it suitable for high-speed communication systems. It also includes an integrated PMOS MOSFET with wide channel availability and high-temperature protection capability, making it suitable for high temperature and harsh environments.

RT7021BGS gate drivers can also be used in systems that require power management functions. For example, they can be used to control the current through a MOSFET, IGBT or power device during operation. This helps to ensure that the maximum power dissipation across the device stays within safe levels. It also helps to reduce power consumption by limiting the power consumption of the power device itself. The maximum current capability of the RT7021BGS motor control application is 2A.

RT7021BGS gate drivers can also be used in system-on-chip (SoC) applications. It is designed to be compatible with multiple SoC platform architectures, and its advanced features such as integrated temperature sensors, and over-current protection, make it suitable for a wide range of SoC technologies.

In addition to its motor control and SoC applications, RT7021BGS also provides intelligent fault management, which helps to protect against adverse environmental conditions such as over-temperature and overtemperature protection, as well as over-load protection.

RT7021BGS gate drivers provide a versatile package of sophisticated gate driving circuits and advanced protection capabilities that are essential for creating low power, energy efficient electric circuits, while also providing reliable protection against current surges, temperature extremes, and other environmental factors. It is a suitable choice for applications that require power management functions, such as motor control, switched-mode power supplies, and SoC applications.
