The HIP2100EIBZ is a high-performance gate driver IC specifically designed for powering transistors used in medium and high-power applications. It is a two-channel gate driver for N-channel MOSFETs and IGBTs, and packs a variety of features designed to simplify the design and engineering of high-performance power supply systems. This article will look at the HIP2100EIBZ application field and working principle.

Features and Benefits

The HIP2100EIBZ offers many features designed to increase performance and reliability of the overall power system. It contains two circuit channels, each with a high and low side driver, along with associated control logic circuits, a charge pump, and power and signal pins. Each channel has a maximum drive current of 4.5A, and can comfortably handle peak currents of over 10A. The charge pumps are capable of driving up to 10A, and the gate drive voltages can be adjusted to provide the best performance under various conditions. The driver features a fault-detection circuit, which automatically shuts down the part when either of the outputs exceeds the maximum safe operating voltage. This feature makes it incredibly reliable in high-stress situations.

The HIP2100EIBZ also offers a variety of features specifically designed to simplify the design and engineering of power supplies. It has a built-in pulse-width-modulation (PWM) signal filter, which filters out any unwanted high-frequency noise from the power signal. This helps prevent undesirable electromagnetic interference (EMI) from affecting the power system, reducing risks of system degradation. Additionally, the device features an adjustable deadtime control, which helps reduce switching losses, improve performance, and enhance system stability. Finally, the device includes a logic level shifter circuit, which helps ensure compatibility with logic interfaces.

Application Field

The HIP2100EIBZ is designed for power systems found primarily in automotive and industrial applications. The device provides a compact and efficient solution for powering transistors used in small to medium voltage switching power supplies, high power inverters, and DC-DC converters. It is suitable for applications such as cooling fans, power supplies, DC-DC converters, motor drives, and similar other medium and high-power applications. Its adjustable deadtime control makes it suitable for controlling motors, which require precise and consistent timing.

Working Principle

The working principle of the HIP2100EIBZ is based on the switch-mode power supply (SMPS) circuit to pump and control current to the device. The device features two independent circuit channels, each with its own control logic, driver, and charge pump. The control logic works by monitoring the gate voltage of the device and conducting a transfer of charge to the gate whenever needed. The power is then routed between the source and the gate, which regulates the flow of current.

The charge pump works by boosting the output of the driver to a higher voltage, thus providing a much faster switching speed compared to a standard voltage driver. It also helps reduce the amount of power wasted by the device due to the faster switching speeds. Additionally, the adjustable deadtime control feature helps reduce switching losses and improve performance.

Conclusion

The HIP2100EIBZ is a powerful and versatile gate driver IC designed for high-performance power systems. It offers a variety of features designed to improve system performance, including a maximum drive current of 4.5A, two independent circuit channels, an adjustable deadtime control, an integrated PWM filter, and a fault-detection circuit. The device is suitable for applications in automotive and industrial systems, such as cooling fans, power supplies, DC-DC converters, and motor drives. With its comprehensive set of features, the HIP2100EIBZ is an essential component for powering transistors in high-power applications.
