IRS2128PBF

IRS2128PBF is a 600V, 1.8A Bi-Directional Gate Driver Integrated Circuit, providing an efficient and easy-to-use solution for driving IGBTs and MOSFETs. It is part of the PMIC (Power Management Integrated Circuit) family of Gate Drivers. It supports high voltage levels from 600V down to 5V levels. The device supports two control inputs so that it can be used in both half-bridge and full-bridge configurations, enabling bidirectional control of both IGBTs and MOSFETs.

The IRS2128PBF is a high-side and low-side drive with a wide operating voltage range (up to 600V) and a current rating of 1.8A. It is designed to reduce EMI and RFI interference, while still performing reliability. The power supply range that it supports is from 5V to 600V. The device also supports multiple turn off control configurations such as active high, active low, series connection and parallel connection.

The IRS2128PBF is used in applications such as motor control, industrial machinery, solid state relays, UPS, solar power, and home appliance. The cost-effective gate driver integrated circuit can be used for both half-bridge and full-bridge configurations, which allows for bidirectional control of IGBTs and MOSFETs. The device comes in a very small package with a low profile, making it a perfect solution for both users who want to reduce the device’s footprint and for those who simply want to reduce the device’s overall cost.

The internal logic control of the IRS2128PBF helps with the protection of external circuits by providing a built-in isolation capability. The isolation logic provides both high and low voltage supply circuits with a safe working range, protecting the external components from incorrect logic signal inputs and preventing destruction in the event of a short circuit. The device allows for a multitude of positive and/or negative start-up options, providing users with more flexibility when configuring their systems. In addition, it also allows for voltage inversion and phase-shift control.

The primary operating principle of the IRS2128PBF is that it uses two complementary MOSFETs – the low side FET and the high side FET – to switch the load. The control signals of the FETs are connected to the logic inputs of the device, and the logic signals are converted to the appropriate voltage levels to control the MOSFETs. The device can be designed to use either PWM or fixed current operation, depending on the application, and features a very low on-resistance as well as low static power consumption. It also provides thermal protection, over-voltage protection, reverse-voltage protection, and other features.

In conclusion, the IRS2128PBF is an ideal choice for applications that require efficient and reliable bi-directional control of IGBTs and MOSFETs. It comes in a small package with wide operating voltage range, allowing for multiple positive and/or negative start-up options and providing users with more flexibility when configuring their systems. It also includes logic control and integrated isolation capabilities to protect against short circuits and other damage. All in all, the IRS2128PBF offers an efficient and cost-effective solution to a variety of applications.
