It is designed to enable extended battery life and improved system performance in a wide range of applications, including automotive, home-automation, industrial, medical, and wearable technologies.

For example, automotive applications can use the MC33772BSP2AER2 to manage functions such as battery charging and power distribution. The PMIC also provides power-galvanic isolation for safety, along with Smart Power Selector (SPS) and LED drivers for power and lighting control. The MC33772BSP2AER2 can also be used in medical and industrial applications to detect, manage, and protect power distribution boards from dangerous over-current, over-voltage, and over-temperature conditions.

In addition to automotive applications, the MC33772BSP2AER2 is also suitable for home-automation, industrial, medical, and wearable technologies. It supports external high-side drivers to control and monitor power distribution and circuitry, and can manage multiple power rails and system loads simultaneously. It also supports power sequence switching and power failure conditions, with support for I2C, SPI, LIN, SSC, and UART interfaces.

MC33772BSP2AER2 Working Principle

At the core of the MC33772BSP2AER2 PMIC is its ability to regulate, monitor and protect a system’s power supply. This is accomplished through voltage regulation, power sequencing, measurement, monitoring, and protection. To coordinate these functions, the MC33772BSP2AER2 employs an array of protection and logic circuits.

At the heart of the PMIC’s power-management system is a voltage-regulator block. This is responsible for providing a regulated supply voltage from the battery or from an external voltage source. On the output side, the MC33772BSP2AER2 provides power switching and sequencing, along with over- and under-voltage protection, short-circuit protection, over-current protection, and over-temperature protection.

The MC33772BSP2AER2 also features Smart Power Selector (SPS) to help manage system power distribution. This is a physical switch that uses digital logic to automatically select the best power source for a given application. For example, if the primary power source fails or drains too quickly, SPS can choose a secondary source, such as an auxiliary battery, to supply power to the system.

The MC33772BSP2AER2 also includes voltage-isolation circuitry to help protect the system from the frequently changing environment and power fluctuations of typical automotive applications. This helps to ensure that power-management protocols are always followed.

In addition to power-management functions, the MC33772BSP2AER2 also provides system health diagnosis and control features. With this, OEMS can monitor the system for temperature and voltage changes, and adjust their design and power-management strategies accordingly.

Finally, the MC33772BSP2AER2 features low-current and low-quiescent power consumption, making it an ideal choice for ultra-low-power applications. Its integrated sleep modes, when combined with its fast wake-up time, make it suitable for low-power wake-up applications as well.

Conclusion

The MC33772BSP2AER2 battery management system is an ideal choice for system power rail regulation, including battery charging, protection, power-switching, voltage regulation, and power supply sequencing. It is designed for automotive, home-automation, industrial, medical, and wearable technologies, and provides a range of benefits, including advanced power-management solutions in a small package, Smart Power Selector (SPS), voltage-isolation circuitry, system health diagnosis, and low-power consumption.
