Introduction

The IR3500MTRPBF is a member of the Intelligent Power Module (IPM) family of high-performance, integrated power-managment devices. It integrates a wide range of power-management, current-control, and protection functions in a single-chip solution. The IR3500MTRPBF IPM provides an efficient, high-performance power-management-solution, which enables the user to save board space, reduce components and development time.

Application and Working Principle

The IR3500MTRPBF is primarily used in DC-DC conversion, clamped inductive switching, and power supply sequencing applications. Its integrated circuit architecture and software allows it to provide protection against any kind of overvoltage, current overshoots, and other transient load conditions. The IR3500MTRPBF has a host of integrated features that provide protection from any kind of faults in a power system. The IR3500MTRPBF adopts a 2-level MOSFET drive system for high performance, fast response time, and low switching losses. This system provides a much higher efficiency than a traditional FET driver. The IR3500MTRPBF is capable of controlling two independent power-management channels with an input voltage range of 1.25V to 18V, and an output voltage range of 1V to 6V. The IR3500MTRPBF features an integrated, 3-phase high-current, MOSFET-gate driver, with a maximum current of 30A per channel. It includes an integrated N-channel MOSFET and P-channel MOSFET in parallel, to provide a low-Rds ON, high-current switching solution. The maximum peak output current of the MOSFET is up to 40A. The IR3500MTRPBF also features an integrated, 2-level smart-clamping system, which provides adjustable clamping voltages for overvoltage protection. This system can be used to protect the power stage from currents overshoots in the system. Additionally, the IR3500MTRPBF provides an integrated I2C interface for control and monitoring of the power devices. The IR3500MTRPBF also features current-limiting protection and thermal-shutdown protection. The current limiting protection limits the MOSFET current during any kind of fault condition, while the thermal-shutdown protection ensures that the system is protected from overheating.In conclusion, the IR3500MTRPBF is a highly integrated, powerful power-management device that can be used in a variety of applications. It integrates a wide range of protection and control features, and provides fast response times with high efficiency. It is an ideal solution for any power management system.
