Introduction

BD9582F-E2 is a highly integrated power management integrated circuit (PMIC) for electromobility and power management applications. It features superior system level integration and enhanced power supply stability, enabling lower component count and reduced system complexity. With its integrated protection circuits that are suitable for automotive applications, it provides system level protection and high reliability.

Application Field of BD9582F-E2

The BD9582F-E2 is designed for use within battery systems and other electromobility related applications. Its flexibility allows it to meet the needs of a wide variety of automotive applications, including on-board charging systems, regenerative braking systems, hybrid/electric vehicle (HEV/EV) powertrain management, power distribution systems, inverter/power conversion system control, and smart charging systems. With its wide input voltage range, it can also be used in industrial, portable, and other battery equipment.

The BD9582F-E2 is particularly well-suited for electromobility systems because it provides optimal power performance, robust system-level protection, and integration into powertrain control systems. It offers high system integration with a wide input voltage range, fast transient response, and extended output current capabilities. With its integrated extensive fault protection measures, it ensures reliable and safe operation of the system against overvoltage, undervoltage, overcurrent, and temperature related issues.

Working Principle of BD9582F-E2

The BD9582F-E2 provides optimized power management for electromobility and battery systems by combining multiple power supply rails into one integrated circuit. It contains an integrated dual-channel step-down regulator, an output voltage tracking system, a voltage detection system, an open circuit voltage detection system, a power on reset system, and temperature compensated current-limit protection. These components work in tandem to provide system level optimization and protection.

The first component is the dual-channel step-down regulator, which is used to transform the input voltage into a regulated output voltage to drive the rest of the system. The output voltage tracking system is used to ensure that the output voltage is always maintained at a stable level, even if the input voltage fluctuates widely. The voltage detection system monitors the input and output voltages and shuts down the system if either falls outside the range of safe operation. The open circuit voltage detection system monitors the current level in the system and shuts it down if the current drops below a specified level. The power on reset system is used to reset the system after shut down, and the temperature compensated current-limit protection monitors the temperature of the system to ensure safe operation.

The BD9582F-E2 also supports communication with external devices via I2C and SPI interfaces, enabling monitoring and control of power management parameters. It also supports a battery management system (BMS) output pin, allowing a simple connection to an external BMS system.

Conclusion

The BD9582F-E2 is a highly integrated PMIC designed specifically for electromobility and power management applications. Its integrated protection circuits and wide input voltage range make it suitable for automotive applications, and its excellent system integration provides optimum power performance and improved power supply stability. With its integrated current-limit protection and communication via I2C and SPI interfaces, it enables simple connection to external battery management systems and provides robust system-level protection.
